If you’re planning a national park trip this year, here’s the headline. 2026 is the year the reservation era went into reverse. Glacier, Yosemite, Arches, and Mount Rainier all dropped their entry reservation systems, which means four of the parks that defined the 8am booking scramble are back to drive-up access for the first time in years.
That leaves a much shorter list of places where you need something in hand before you show up. We’ll give you the direct answer first, then walk through every system park by park, because the details matter and they’re different everywhere.
A note from us. We keep this page updated as parks announce changes, and every claim here is checked against the National Park Service and Recreation.gov. If you spot something that’s changed or have a question about your trip, drop us a comment below and we’ll get you an answer.
The Short Answer for 2026
Only one national park in the entire system requires a reservation just to drive through the gate during peak hours, and that’s Rocky Mountain. Beyond that, a handful of parks require a booking for a specific road, area, or arrival method. Here’s the full list of what you need to enter somewhere in 2026.
117 public lands destinations are under threat. Get the free briefing that 27,000+ people use to stay informed and take action.
- Rocky Mountain National Park requires a timed entry reservation to enter the park between 9am and 2pm, May 22 through October 12.
- Muir Woods National Monument requires a parking or shuttle reservation for every single arrival, all year long.
- Haleakala National Park requires a reservation to enter for sunrise, between 3am and 7am.
- Carlsbad Caverns National Park uses timed entry tickets for the cavern itself, and you should treat them as required.
- Acadia National Park requires a vehicle reservation for the Cadillac Summit Road only, May 20 through October 25.
- Shenandoah National Park requires a day-use ticket for everyone hiking Old Rag, March 1 through November 30.
That’s it. Every other park in the system lets you drive in with nothing but an entrance pass, though several have wrinkles worth knowing about, and the marquee experiences inside some parks still run on lotteries and permits. We cover all of it below.
Every 2026 Reservation System at a Glance
| Park | What you need | When it applies | Cost | When to book |
|---|---|---|---|---|
| Rocky Mountain | Timed entry reservation (two types) on Recreation.gov | 9am to 2pm daily, May 22 to Oct 12 (Bear Lake corridor 5am to 6pm, to Oct 18) | $2 processing fee | Monthly releases at 8am MT, plus next-day release at 7pm MT |
| Muir Woods | Parking or shuttle reservation at GoMuirWoods.com | Every day, all arrivals | $10 standard vehicle, shuttle $3.75 per adult, plus $15 per person entrance fee | 90 days ahead, small batch held for 5 days out |
| Haleakala | Sunrise vehicle reservation on Recreation.gov | 3am to 7am daily, year round | $1 per vehicle plus entrance fee | 60 days ahead at 7am HST, second batch 2 days ahead |
| Carlsbad Caverns | Timed entry cavern ticket on Recreation.gov | All cave entries, daily | $1 reservation plus $15 per person at the visitor center | 30 days ahead, sells out in busy seasons |

The Parks That Dropped Reservations for 2026
This is the biggest story in park access in years, so let’s give it the space it deserves. Four parks that required some form of entry reservation in recent summers require none in 2026.
Glacier National Park
For the first summer since 2020, Glacier does not require vehicle reservations anywhere. Not on Going-to-the-Sun Road, not in the North Fork, not at Many Glacier or Two Medicine. The park confirmed it directly, and it’s a genuine change of era after five summers of shifting corridor rules and 8am booking drops.
Two new wrinkles replace the old system, and they matter if Logan Pass is on your list. Parking at the pass is limited to three hours from July 1 through September 7, enforced around the clock with a free dashboard permit from a kiosk. And the free hop-on shuttle is gone, replaced by a ticketed shuttle pilot where every rider age 2 and up needs a ticket booked on Recreation.gov for a $1 fee. Those tickets are released 60 days out on a rolling basis, with leftovers dropping at 7pm Mountain Time the night before, and demand has been fierce. If you’re hiking the Highline, the shuttle ticket is effectively your reservation. We break down the schedule, the sellouts, and the workarounds in our full Glacier reservations explainer, and our guide to the Glacier National Park hub can help you pick your window.
One caveat the park has been upfront about. Vehicles may be temporarily diverted when areas like Many Glacier fill up. No reservations doesn’t mean unlimited room. It means first come, first served, and the early bird still wins.
Yosemite National Park
Yosemite announced in late December 2025 that it would not require day-use reservations at any point in 2026. Instead the park is leaning on real-time traffic monitoring, active parking management in the Valley, and added staffing at key intersections. The early returns have been bumpy. Over Memorial Day weekend, entry waits stretched past 90 minutes and Valley parking filled by mid morning, according to reporting from the Deseret News and ABC7. Our advice is the same as it’s always been. Arrive before 8am or after 4pm, especially on summer weekends, and read our month by month guide to Yosemite before you pick dates.
Arches National Park
Arches lifted its timed entry requirement on February 18, 2026, ending a pilot that began in spring 2022. You can now enter at any hour the park is open. The park service hasn’t said whether the change is permanent, and locals expect the old morning crush at the gate to return, so the webcam at go.nps.gov/archeswebcam is your friend. Fiery Furnace trips and Devils Garden Campground still require reservations. We cover the whole story, including what the gate looks like now, in our Arches timed entry explainer.
Mount Rainier National Park
After piloting timed entry at Paradise and Sunrise in 2024 and at Sunrise in 2025, Mount Rainier announced on February 25, 2026 that it will not require timed entry reservations for any portion of the park this year. The park is managing parking instead and suggests arriving before 7am or after 4pm on busy days. Paradise on a July weekend will test your patience either way. Our list of the best things to do at Mount Rainier includes plenty of corners the crowds skip.
Parks That Still Require a Reservation in 2026
Rocky Mountain National Park
Rocky Mountain is the last park standing with full timed entry, and it runs two systems side by side. A standard Timed Entry reservation covers the park outside the Bear Lake Road corridor and is required from 9am to 2pm daily, May 22 through October 12. A Timed Entry + Bear Lake Road reservation covers the whole park including the Bear Lake corridor and is required from 5am to 6pm daily, May 22 through October 18. Yes, Bear Lake starts at 5am. The sunrise crowd learned that the hard way.
Both types are booked on Recreation.gov for a $2 fee. Reservations are released in monthly batches at 8am Mountain Time on the first of the month, one month ahead, and a second batch drops at 7pm Mountain Time the night before each entry date. You get a two hour arrival window, photo ID is checked against the reservation holder, and a camping reservation or wilderness permit substitutes for timed entry. Arrive before the window starts or after it ends and you drive in free of the system entirely, which is the single most useful loophole in the park system. We walk through every detail, including the Bear Lake re-entry rule, in our Rocky Mountain timed entry explainer, and our guide to the best time to visit Rocky Mountain covers the seasonal strategy.
Muir Woods National Monument
Muir Woods has run the strictest system in the country since 2018, and it isn’t going anywhere. Every arrival needs a reservation, whether you’re parking a car or riding the shuttle, every day of the year. Standard parking runs $10 per vehicle under 17 feet with a 30 minute arrival window, oversized vehicles pay $30 to $45, and shuttle seats are $3.75 per adult round trip. The $15 per person entrance fee is separate. Book at GoMuirWoods.com up to 90 days ahead, and note that weekends genuinely sell out. A small batch of reservations is held back and released 5 days out if you missed the window.
Two practical notes. There’s no roadside parking anywhere near the entrance, so showing up without a reservation simply doesn’t work. And there’s no cell service or Wi-Fi at the monument, so download or print your pass before you leave.
Haleakala National Park (Sunrise Only)
To drive into the summit district of Haleakala between 3am and 7am, you need a sunrise reservation. It costs $1 per vehicle on Recreation.gov, on top of the regular entrance fee, and the person named on the reservation has to be in the car with photo ID and a copy of the confirmation. Reservations open 60 days ahead at 7am Hawaii Standard Time and the park says popular dates can vanish within fifteen minutes. A second batch is released 2 days ahead, also at 7am HST, and that’s the one most folks on a spontaneous Maui trip end up chasing. You’re limited to one sunrise reservation per three day period, and there are no refunds or exchanges if the summit is socked in. Weather at 10,000 feet makes its own plans.
If you miss out, sunset at the summit requires nothing at all and is nearly as good. Neither does arriving any time after 7am to hike the crater. Our guide to the best time to visit Haleakala has the full seasonal picture.
Carlsbad Caverns National Park
Carlsbad sells timed entry tickets for the cavern on Recreation.gov for $1, with the $15 per person entrance fee paid at the visitor center when you arrive. Here’s the honest fine print. The park’s own pages are inconsistent right now, with the fees page saying a timed entry reservation “must be purchased” and other pages calling it strongly recommended. Our advice is to treat it as required, because entry times do sell out in busy seasons and the drive to Carlsbad is too long to gamble on. Reservations open 30 days ahead. Ranger-led tours are temporarily suspended as of this writing, so the self-guided Big Room and Natural Entrance routes are the show, and they’re a tremendous one. Start with our guide to the best things to do at Carlsbad Caverns.
Acadia National Park (Cadillac Summit Road Only)
You can enter Acadia any time without a reservation. The one exception is driving the Cadillac Summit Road, which requires a $6 vehicle reservation from May 20 through October 25, 2026, booked on Recreation.gov. The split release is the thing to understand. 30% of reservations go live 90 days ahead and the remaining 70% drop just 2 days ahead, both at 10am Eastern, so the short window is actually your best odds. Sunrise reservations come with a 90 minute entry window and a limit of one per seven days, daytime reservations get a 30 minute window and one per day, and there’s no re-entry. Vehicles over 21 feet, including bike racks, are prohibited.
Cadillac is the only spot in the park where this applies. The Park Loop Road, Jordan Pond, Sand Beach, and everything else just need an entrance pass, and the fare-free Island Explorer bus covers most of the park from late June through mid October. Our month by month Acadia guide has the full picture.
Shenandoah National Park (Old Rag Only)
Entering Shenandoah requires nothing beyond an entrance pass. Hiking Old Rag does. From March 1 through November 30, everyone on the Saddle, Ridge, and Ridge Access trails needs a $2 day-use ticket from Recreation.gov, every person in your group, kids included. The park caps it at 800 tickets per day, with 400 released 30 days ahead and 400 released 5 days ahead at 10am Eastern. Tickets are not sold at the entrance station, and rangers do check on the mountain.
One heads-up for 2026. The main Old Rag parking lot closed May 4 for a construction project expected to run into November, so you’ll be parking in Lot 2 or the grassy overflow lot on Nethers Road. Build in a few extra minutes.
No Reservation Needed, but Know the Fine Print
A few parks don’t require reservations but run systems that surprise first-timers.
- Zion has no entry reservation, but private cars can’t drive the Zion Canyon Scenic Drive during shuttle season, which runs March 7 through November 28 in 2026 plus the week after Christmas. The shuttle is free with no ticket needed, you just queue for it. The famous hikes are a different story, which we cover in the lottery section below. See our best time to visit Zion guide, and note the park’s 2026 fee and permit changes.
- Great Smoky Mountains has no entrance fee and no reservation, but any vehicle parked longer than 15 minutes needs a parking tag. They’re $5 daily, $15 weekly, or $40 annual, sold at kiosks, visitor centers, and online, and there’s no cap on how many are sold. It’s a fee, not a reservation, so you can’t be locked out. Our guide to the best time to visit the Smokies helps you dodge the crowds anyway.
- Yellowstone and Grand Teton require nothing to enter in 2026 beyond an entrance pass. Both made our fact checks this spring, and neither has ever run an entry reservation system.
Permits for Specific Experiences
Entry is one thing. The bucket-list experiences inside the parks are another, and most of the famous ones run on lotteries or hard capacity limits. Here’s the 2026 state of play.
Angels Landing, Zion
Hiking beyond Scout Lookout to the summit of Angels Landing requires a permit won through a lottery on Recreation.gov. There are two ways in. The seasonal lottery opens quarterly, with applications for September through November hikes running July 1 to 20 and permits issued July 25, and the window for December through February opening October 1. The day-before lottery runs daily from 12:01am to 3pm Mountain Time, with results at 4pm the same day. Either way it’s a $6 application fee covering up to 6 people, plus $3 per person if you win. Rangers check permits on the trail at any hour. No permit is needed for the West Rim Trail up to Scout Lookout, which gets you most of the climbing and a great deal of the view. The Narrows, by contrast, needs no permit for the bottom-up day hike.
Half Dome, Yosemite
The cables route up Half Dome requires a permit every day the cables are up, which in 2026 is expected to be May 22 through October 13. The preseason lottery ran March 1 to 31 with results in mid April, so if you’re reading this now your route in is the daily lottery, which you enter two days before your hike date between 12am and 4pm Pacific on Recreation.gov. It’s a $10 application fee plus $10 per person if you’re drawn. Applications cover up to 6 people. Backpackers can request Half Dome permits with a wilderness permit instead, which is a quieter path to yes.
Fiery Furnace, Arches
Timed entry may be gone at Arches, but the Fiery Furnace still requires a reservation for both self-guided entry and ranger-led trips, booked through Recreation.gov. The maze of fins and slots has no marked trail, so the park keeps numbers low on purpose. Check availability well ahead for spring and fall.
The Denali Road Lottery, Still Suspended
The September Road Lottery at Denali remains suspended, and the park’s official line is that it’s off for the foreseeable future. The Pretty Rocks landslide closed the park road at Mile 43 back in 2021, and while the new Polychrome area bridge is finally nearing completion in 2026, full bus service to the end of the road isn’t expected until 2027. We’d love to see the lottery return after that, but nothing has been announced, so don’t build a trip around it.
Glacier Bay by Private Boat
If you’re piloting your own vessel into Glacier Bay between June 1 and August 31, you need a permit from the park, and the daily quota is just 25 private vessels. First-time entries each year also require an orientation at the Bartlett Cove Ranger Station. Most folks see the park by cruise ship or day tour, where the operator holds the permit and you don’t need a thing.
The Ferry Parks, Dry Tortugas and Channel Islands
Neither park requires a reservation in the technical sense. Both require one in every practical sense, because the boats are the only way in for most folks and the boats sell out.
Dry Tortugas is served by a single ferry, the Yankee Freedom out of Key West, and day trips routinely sell out weeks in advance, with the operator’s camping spots booking out 9 to 12 months ahead. Online bookings open 6 months out. The seaplane is the pricier backup, and it sells out too. Channel Islands runs on Island Packers boats from Ventura, where summer weekends and kayak-friendly crossings fill weeks ahead. If you’re camping on the islands, book the ferry first and the campsite second. That ordering trips people up constantly.
New for 2026, Fees, Passes, and the $100 Surcharge
Reservations aren’t the only thing that changed this year. As of January 1, 2026, the park service rolled out the biggest fee changes in a generation, and they hit international travelers hardest.
- The $100 nonresident surcharge. Travelers who aren’t US residents, age 16 and up, pay an extra $100 per person on top of the regular entrance fee at 11 parks. The list is Acadia, Bryce Canyon, Everglades, Glacier, Grand Canyon, Grand Teton, Rocky Mountain, Sequoia and Kings Canyon, Yellowstone, Yosemite, and Zion. The surcharge is waived if you’re admitted with any America the Beautiful pass or that park’s annual pass, and it’s waived for everyone in a vehicle entering on a passholder’s pass.
- The America the Beautiful annual pass costs $80 for US residents and now $250 for nonresidents. For an international family hitting two or more of the surcharge parks, the $250 pass pays for itself almost immediately, since it covers the passholder’s whole vehicle and waives the surcharge.
- Fee-free days now apply only to US residents. The 2026 dates include Presidents Day (February 16), Memorial Day (May 25), June 14, the July 3 to 5 weekend, the NPS anniversary (August 25), September 17, October 27, and Veterans Day (November 11). Worth knowing both ways, because fee-free days are also the most crowded days of their respective months.
- Passes went digital. Every America the Beautiful pass, including Senior, Military, Access, and 4th Grade versions, is now available in digital form through Recreation.gov, with physical cards still an option. Each pass also now covers two motorcycles instead of one.
How to Actually Get These Reservations
We’ve booked more of these than we can count, and the folks who win the scramble all do the same handful of things.
Set Up Recreation.gov Before You Need It
Nearly everything here runs through one website. Create your Recreation.gov account days ahead, confirm your email, save a payment method, and fill out your profile so checkout doesn’t ask you questions while the clock runs. At release time, be logged in with the exact listing already open. The difference between winners and losers on a Haleakala drop is measured in seconds, and typing a credit card number is where those seconds go to die.
Respect the Clock, and the Time Zone
Every release in this post happens at a specific local time. Rocky Mountain drops at 8am Mountain and 7pm Mountain. Haleakala drops at 7am Hawaii, which is lunchtime on the East Coast. Acadia and Old Rag drop at 10am Eastern. Glacier’s shuttle leftovers drop at 7pm Mountain. Put the converted time in your phone with a five minute warning, because the single most common way folks miss a reservation is doing the time zone math wrong.
The Short Windows Are the Real Game
Almost every system holds back inventory for last-minute release, and those drops are often easier to win than the famous far-out ones. Acadia releases 70% of Cadillac reservations just 2 days ahead. Old Rag holds back half its tickets for 5 days out. Haleakala adds inventory 2 days ahead. Rocky Mountain and Glacier both drop next-day inventory at 7pm Mountain. If your dates are locked and your alarm game is strong, the short window is your friend.
Cancellation churn is the other quiet opportunity. Rocky Mountain reservations can be canceled up to 24 hours out, and plenty are, so sold-out dates regrow availability in the evenings. Checking back at random beats refreshing at noon once and giving up.
Don’t Buy From Scalpers
These reservations are non-transferable, and the busiest systems check photo ID against the reservation holder at the gate. Rocky Mountain checks. Haleakala checks. Glacier’s shuttle checks. A reservation bought secondhand is a reservation that can be refused, and you’ll find out at 4am in the dark.
If You Show Up Without One
It’s not always game over, and it helps to know exactly what happens at each gate.
- Rocky Mountain: enter before 9am or after 2pm without a reservation, or before 5am or after 6pm for Bear Lake Road. The park is fully open to you outside those hours.
- Haleakala: arrive after 7am and the summit district is yours, no reservation needed. You’ll miss sunrise, not the park.
- Acadia: skip Cadillac by car. Hike up it, or catch sunrise from Ocean Path or the Schoodic Peninsula instead.
- Old Rag: no ticket means no hike, full stop. Whiteoak Canyon and the rest of Shenandoah are open to you.
- Muir Woods: you’ll be turned away, and there’s nowhere legal to park within walking distance. Redwood Regional and Samuel P. Taylor are fine same-day alternatives.
- Carlsbad: you may get a walk-up entry time on a quiet day, but on a busy one you’ll wait or miss the cave entirely.
The Bottom Line
After half a decade of expanding reservation systems, 2026 swung the other way. One park requires a reservation to enter during peak hours, five more require a booking for a specific road, area, or arrival, and the rest of the system is back to the old deal, which is that the early bird gets the parking spot. The lotteries for Angels Landing and Half Dome aren’t going anywhere, the ferries to Dry Tortugas and the Channel Islands still book out weeks ahead, and international travelers need to do new math on the $100 surcharge and the $250 pass.
Whether the dropped systems stay dropped is an open question, and nobody at the park service has promised anything about 2027. We’ll update this page the moment anything changes. In the meantime, set the alarms, book the short windows, and go early. The parks reward folks who show up at 6am, reservation era or not.
