White sand, turquoise water, and a marked underwater snorkeling trail.
Trunk Bay is one of the best-known beaches in Virgin Islands National Park, a crescent of white sand and glowing turquoise water on the north shore of St. John, framed by lush green hills. It regularly appears on lists of beautiful beaches, and its combination of soft sand, clear water, and dramatic scenery makes it a classic Caribbean beach experience within a national park.

Learn about Trunk Bay
The underwater snorkeling trail
Just off Trunk Bay's beach lies a coral reef with a self-guided underwater snorkeling trail, a rare feature that makes the reef accessible and educational for visitors. Snorkelers follow a route marked by underwater plaques that point out and identify corals, sea fans, and reef fish, turning a swim into a guided nature walk beneath the surface.
The trail is ideal for beginners and families, since it is close to shore in relatively calm, clear water, though snorkelers should still be mindful of conditions and currents. As always, it is essential never to touch or stand on the coral, which is alive and fragile, and to keep a respectful distance from marine life.
Enjoying the beach
Beyond snorkeling, Trunk Bay is simply a beautiful place to swim, sunbathe, and relax, with soft white sand and warm, shallow water. Because it is a developed beach within the park, it has amenities uncommon on wilder shores: a lifeguard on duty, restrooms and showers, picnic areas, and gear rentals, making a visit easy and comfortable.
There is a small entrance fee for the beach, which helps maintain the facilities. Trunk Bay can get busy, especially when cruise ships visit St. Thomas nearby, so arriving early rewards you with quieter sand and water. However you spend your time, it offers a quintessential Virgin Islands beach day.
