The Best Things to Do in St. Thomas
From world-class beaches and Caribbean snorkeling to the island’s most thrilling adventure — your complete guide to St. Thomas, USVI.
Start with the #1 ExperienceSt. Thomas is one of the Caribbean’s most popular destinations for a reason. This 32-square-mile island is home to some of the region’s most loved beaches, reef-lined cays, and mountainous terrain. It’s a complete tropical destination that appeals to both first-time visitors and returning travelers alike.
As a U.S. territory, St. Thomas requires no passport for American travelers. U.S. dollars and English are spoken everywhere, and the USVI’s duty-free status makes Charlotte Amalie one of the Caribbean’s top shopping destinations. Combine that accessibility with world-class nature and adventure, and you have a Caribbean island that keeps rising on every “best of” list.
This guide covers every major category — relaxing beach days, snorkel excursions, historic landmarks, and adrenaline-fueled adventure. We’ll start where every great St. Thomas trip should: high above Magens Bay, flying through the treetops.
Tree Limin’ Extreme Zipline
If you do only one activity on St. Thomas, make it this. Perched high above Magens Bay on St. Peter Mountain, Tree Limin’ Extreme is the island’s only zipline tour — featuring six ziplines, two sky bridges, and eight aerial treetop platforms, all surrounded by lush tropical scenery and panoramic views of Magens Bay, St. John, Hans Lollick, and the British Virgin Islands.
What sets Tree Limin’ Extreme apart is the finale: the world-famous Yo-Yo Zipline — a forward-and-backward thrill that sends you flying in both directions for the ultimate ride. No other zipline experience in the Caribbean ends like this.
Two expert guides accompany every tour, providing a safety briefing and personal safety gear before you zip through the course built to ACCT safety standards. Whether you’re a first-timer, traveling with kids, or a cruise guest with a few hours on island, this is the experience everyone remembers.
Best Beaches in St. Thomas
St. Thomas has more than 40 beaches, a remarkable number for an island its size. Here are the ones that earn their reputation.
Consistently ranked among the most beautiful beaches in the world, Magens Bay features a pristine, mile-long stretch of white sand. Because it sits inside a protected bay, the water here stays calm and peaceful. The shore is lined with tropical sea grape trees, and the park is fully equipped with amenities like restrooms, beach chair rentals, and a beachside bar. Note that there is a $7 entrance fee for non-locals. Best of all, Magens Bay sits directly below Tree Limin’ Extreme, making it incredibly easy to combine a morning zip with an afternoon relaxing on the sand.
The snorkeler’s beach on St. Thomas. Right off the sand you’ll spot parrotfish, pufferfish, and sea turtles. Adjacent is Coral World Ocean Park making this a full-day destination for families traveling with young children.
Reliably less crowded than the main spots, Secret Harbour features calm waters, incredible snorkeling right off the beach, and a great onsite restaurant, Sunset Grille. It’s the perfect choice for a slow afternoon beach day, especially if you want to avoid the cruise crowds.
Located on the north side of the west end, Hull Bay is the go-to spot for resident surfers during winter swells. The beach offers a raw and unpolished experience, capturing an authentic fishing village vibe with a relaxed beach bar that sets it apart from resort-facing destinations. Come here to see how St. Thomas locals actually spend a day.
Water Sports & Ocean Experiences
Being located in the Caribbean, the ocean around St. Thomas is extremely biodiverse with so much to explore. Here are the best ways to actually get out and experience it.
As a classic St. Thomas excursion, guided catamaran snorkel tours typically make two or three stops, often visiting Turtle Cove, where sea turtle encounters are nearly guaranteed. Most trips include lunch, an open bar, and all your equipment, making this the most efficient way to see the best reefs if you are on a tight schedule.
Virgin Islands Ecotours offers guided kayak expeditions through the largest mangrove lagoon in the USVI, finishing with a snorkel at Cas Cay. Paddling through the lagoon you’ll spot herons, rays, and fish. Great for families who want nature over adrenaline.
St. Thomas sits right next to deep ocean drop-offs, making it one of the best spots for deep-sea fishing. Charter boats head out daily to chase everything from mahi-mahi to tuna and marlin. Whether you are an experienced angler or just looking for a fun day on the water, you can easily book half-day or full-day fishing trips with Neptune or Double Header.
Coki Beach Dive Center offers a “Discover Scuba” experience for non-certified divers, an instructor takes you through the basics on the surface, then accompanies you on a guided shallow dive. No certification required, and the reef is diverse enough that a single 40-minute dive is absolutely worth it.
Charlotte Amalie & Historic St. Thomas
St. Thomas has been a major Caribbean trading port since the 1600s — first under Danish colonial rule, then American from 1917 — and Charlotte Amalie carries that history visibly in its architecture and streetscape.
The waterfront capital is a hillside grid of 18th- and 19th-century warehouses converted into shops, restaurants, and galleries. Main Street is the center of action, a tax-free shopping strip with jewelry, rum, and local art. Explore the side streets lined with Danish colonial buildings painted in true Caribbean fashion.
Built in the 1700s using ballast bricks from Denmark, the 99 Steps climb steeply from the lower town to Blackbeard’s Castle above (there are actually 103, count them!). At the top, the views across Charlotte Amalie Harbor are among the best on the island.
This Danish watchtower dates to 1679 and anchors a hilltop property above the 99 Steps with gardens and panoramic harbor views. Named for the legend that pirate Edward Teach (Blackbeard) used the tower as a lookout.
An outdoor marine park built around an underwater observatory. A three-story tower sunk into the reef where you descend below the water line to observe reef fish, nurse sharks, and rays. Above water: touch tanks, sea turtle encounters, and a stingray pool. A strong half-day option for families with young children.
More Adventures & Scenic Experiences
Paddle through the calm waters off Frenchman’s Reef in a clear-bottom kayak illuminated by LED lights. Watch for sea turtles, stingrays, tropical fish, and other marine life beneath you while enjoying a peaceful evening on the water under the stars. Perfect for families and first-time kayakers.
Two of the island’s most popular overlooks sit on the ridge above Magens Bay. Drake’s Seat looks out over Magens Bay and the Atlantic side of the island. Mountain Top at 1,547 feet is the highest road-accessible point on St. Thomas, with views of neighboring islands.
Guided UTV tours are a great non-water experience on island. Adventure through mountainous roads, past scenic overlooks, and beaches that are difficult to reach by car. A good option for groups who want an active exploration without committing to a full day on the water.
Take a short ferry ride from Red Hook Ferry Terminal to St. John, where over two-thirds of the island is protected as Virgin Islands National Park. Spend the day exploring pristine beaches and scenic trails, including snorkeling the underwater trail at Trunk Bay or hiking the lush Reef Bay Trail. Ferry service is available for both passengers and vehicles.
