We have stood at the Trunk Bay overlook on St. John at sunrise with the road to ourselves, and we have fought for a parking spot at 11 a.m. when three tour buses arrived at once. Both versions of this beach are worth the trip. Trunk Bay sits inside Virgin Islands National Park, and it is the single image most people picture when they picture the Caribbean: a crescent of white sand, water that shifts from clear to turquoise to deep blue, and a small green island, Trunk Cay, parked just offshore.
This is a field guide based on our own time on the island. It covers how to get there, where to park, when to go, what the snorkeling is actually like, and what changed after Hurricane Maria so you know what to expect when you arrive.
The Quick Version
- Where: North Shore Road, St. John, U.S. Virgin Islands, inside Virgin Islands National Park
- Getting there: Ferry from St. Thomas to Cruz Bay, then about a 10 to 15 minute drive (or taxi) to the beach
- Fee: There is a per-person entrance fee for the developed Trunk Bay beach area; check the NPS site for the current rate before you go
- Parking: Roughly 40 spots at the main lot plus overflow across the road; it fills fast mid-morning
- Best time of day: Sunrise to about 9 a.m. for empty sand and soft light
- Highlight: The marked underwater snorkel trail along Trunk Cay
Getting to Trunk Bay
St. John has no airport. You fly into St. Thomas (STT), take a taxi to the ferry terminal at Red Hook or Charlotte Amalie, and ride the passenger ferry across to Cruz Bay on St. John. From Cruz Bay, Trunk Bay is about a 10 to 15 minute drive northeast along North Shore Road (Route 20).
Most visitors get there one of three ways: a taxi from Cruz Bay, a rental car or open-air Jeep, or a guided tour. Renting on St. John is its own adventure. Roads are narrow and steep, and everyone drives on the left, which catches first-timers off guard. If you are not comfortable with that, a taxi is the easy call.

Parking, Fees, and Facilities
The main lot holds roughly 40 cars, with overflow parking across the road. By late morning on a cruise-ship day it can be full, which is the strongest argument for an early start. From the lot, a short paved path of a few hundred feet leads down to the sand, so it is an easy walk for most visitors and largely accessible.
Trunk Bay is the one developed beach in the park, which means it charges a per-person entrance fee and offers facilities that the wilder beaches do not: restrooms, outdoor showers, changing rooms, picnic areas, and snorkel-gear rental on site. Restrooms and shower facilities generally run roughly 8 a.m. to 4 p.m., while the beach itself is open around the clock. Fees and hours change, so confirm the current numbers on the official park page before you arrive.
Best Time to Visit
Go early. The best window is sunrise to about 9 a.m., before the day-trip crowds and cruise excursions roll in. The light is soft, the water is calm, and you can sometimes have a fair stretch of the beach to yourself. By midday it becomes a busy, happy beach scene, which is fine if that is what you want.
Season matters too. December through April is the dry, busy high season with the most reliable weather. Hurricane season runs June through November, with the highest risk from August into October. We have had beautiful days in the shoulder months, but watch the forecast if you travel then.
Snorkeling and the Underwater Trail
The signature feature here is the self-guided underwater snorkel trail that runs along the edge of Trunk Cay. Submerged signs identify reef features and marine life as you float the loop. It is short and beginner-friendly, which makes it a good first reef for kids and anyone new to a mask and snorkel.
Set your expectations honestly. The 2017 hurricanes and ordinary reef stress took a toll, and much of the bay floor is sandy rather than dense living coral. You will still see fish, rays, and, with luck, a green sea turtle grazing the seagrass. The water is warm and clear, and the trail is an easy, enjoyable float rather than a world-class reef dive.
You can rent snorkel gear at the beach concession if you would rather travel light. If you bring your own, a simple mask, snorkel, and fins set is all you need for the trail.
Best Photo Spot
The classic postcard shot comes from the overlook on North Shore Road above the beach, where you get the full curve of sand, the colors of the water, and Trunk Cay in one frame. The pullout is small and also used by tour buses, with little real parking, so be quick and be careful. If you stop along the road instead, watch for oncoming traffic on the blind curves.
Know Before You Go
- Reef-safe sunscreen only. The U.S. Virgin Islands banned the import, sale, and use of sunscreens containing oxybenzone, octinoxate, and octocrylene. Bring a mineral, reef-safe sunscreen, and apply it before you reach the water.
- Do not touch the sea turtles. Green sea turtles are protected under the Endangered Species Act. Give them plenty of room and admire from a distance.
- Wear something on your feet. The path is easy, but warm sand and the occasional rough patch make sandals worth it.
- Pack snacks and water. Food options at the beach are limited. Stock up in Cruz Bay, a short drive away, where the prices beat the island grocery markup.
- Confirm current fees and hours on the official Virgin Islands National Park page before your visit.
After Hurricane Maria: What Changed
Hurricanes Irma and Maria hit St. John hard in September 2017, and the island still carries the marks. At Trunk Bay, many of the palms were stripped or leveled, though some survived and the green is steadily returning. Most photos you will see of the beach, including ours, show it in its present condition rather than the way it looked before the storms.
One lasting change worth knowing: Caneel Bay, long the only resort inside the park, was destroyed in the 2017 storms and has remained closed for years amid a drawn-out dispute over its future. The nearest hotels and rentals are now back in and around Cruz Bay. None of this takes away from the beach itself, which remains one of the most beautiful stretches of sand in the Caribbean.
