St. Thomas Activities: Beaches, Snorkeling, and the St. John Ferry
St. Thomas gets filed away as a cruise stop, and it does welcome a lot of ships. But I book more week-long stays on the island than cruise add-ons, because the best St. Thomas activities reveal themselves after the ships pull out at 5 p.m. This guide covers a full vacation in St. Thomas, Virgin Islands, covering beaches, snorkeling, the St. John ferry, food, nightlife, and where to base yourself.
One more perk up front: the USVI is a U.S. territory, and Americans can fly in without a passport.
If you only have one day in port, my guide to things to do in St. Thomas on a cruise day is the better fit. Everything below assumes you have at least three or four nights.
Quick Take
Magens Bay charges $5 per adult plus $2 to park; kids under 12 enter free.
The public ferry from Red Hook to Cruz Bay, St. John departs about every hour, takes 20 minutes, and costs $8.15 each way for adults.
U.S. citizens fly in with a government-issued photo ID, with no passport required.
High season runs mid-December through April; September and October carry the greatest hurricane risk.
Driving is on the left, even though the cars are American models with the wheel on the left.
U.S. residents get a $1,600 duty-free allowance when returning home, double the standard Caribbean limit.
St. Thomas Beaches Worth Planning Around
Magens Bay is the famous one, and it earns the reputation: a mile of calm water inside a deep, protected bay, with lifeguards, restrooms, a cafe, and rentals. Admission is $5 for adults, kids under 12 are free, and parking runs $2. Gates open at 7 a.m.; overnight visitors should go early or after 2 p.m., once ship passengers clear out.
The rest of the island is where a multi-day trip pays off.
Magens Bay: Calm, mile-long, full amenities. $5 adult plus $2 parking
Coki Point: The island's easiest walk-in snorkeling. Free entry
Sapphire Beach: Views across to St. John, steady breeze. Free entry
Secret Harbour: Gentle water, ideal for kids and beginners. Free entry
Lindquist Beach: Quiet, undeveloped territorial park. Small per-person fee
Brewers Bay: Resident turtles, planes landing overhead. Free entry
If I had to pick two, I'd take Coki Point for the fish and Lindquist for a quiet afternoon. Hull Bay on the north side is the local favorite, with tree cover and a winter surf break. Fees do change, so treat the figures above as a 2026 snapshot.
Snorkeling and Diving in St. Thomas, Virgin Islands
Coki Point is the easiest win on the island. Wade in off the beach and the fish appear within minutes; vendors rent gear a few steps from the water. Secret Harbour has a mellow route along the rocks on its left edge that suits first-timers, and Brewers Bay is the one for turtles. Go in the morning before the wind picks up.
By boat, the classic half-day trips run to Turtle Cove at Buck Island, Christmas Cove, and the reefs around Great St. James. Divers head for Cow and Calf Rocks and the wreck of the Cartanser Senior. Expect half-day catamaran outings to cost roughly $85 to $150 per person; operators adjust rates often.
I compare options and book most of my independent tours through Viator. Some links are affiliate links, which support the site at no cost to you. For a full ranking of the boat operators, my list of the best St. Thomas cruise excursions applies to overnight guests too. The same companies run longer departures for travelers who aren't racing a ship's all-aboard time.
The St. John Day Trip From St. Thomas
Ask me for the single best thing to do in St. Thomas, Virgin Islands and my answer is a day on St. John. The public ferry leaves Red Hook for Cruz Bay about every hour, takes 20 minutes, and costs $8.15 each way for adults; kids ages 2 to 11 ride for $1. No reservation needed. Buy a ticket at the window and walk on.
Two-thirds of St. John is Virgin Islands National Park, which keeps the island green and its shoreline blissfully undeveloped. Trunk Bay charges a $5 amenity fee for visitors 16 and up and has the famous underwater trail. Maho Bay is where turtles graze a few yards off the beach, and Honeymoon Beach is a 20-minute walk from Cruz Bay on the Lind Point trail.
Taxis meet every ferry and shuttle people to Trunk and Maho, or you can rent a Jeep in Cruz Bay to reach the quieter east end. Check current fees and any closures on the official Virgin Islands National Park fees page.
Top St. Thomas Virgin Islands Attractions on Land
Coral World Ocean Park is the headline attraction for families: an undersea observatory, touch pools, and animal encounters, with general admission at $29 for adults and $17 for kids ages 3 to 12, open daily from 9 a.m. to 4 p.m. It sits right next to Coki Point, so pair the two into one outing.
In Charlotte Amalie, climb the 99 Steps, browse the duty-free jewelry and liquor along Main Street, and ride up to Mountain Top for a banana daiquiri with a view over Magens Bay. Drake's Seat, a roadside overlook above the same bay, makes an easy two-minute photo stop.
The Skyride to Paradise Point lifts you 700 feet above the harbor, but it operates mainly on days when ships are in port, so check the posted schedule first. The USVI tourism department posts an events calendar at VisitUSVI.com; the biggest party of the year is Carnival, held each spring.
Food and Nightlife on St. Thomas
Eat at least one pate, a fried pocket of spiced beef, chicken, or saltfish, from a roadside stand, and order callaloo or fresh mahi wherever you see them. Frenchtown, a compact old fishing quarter just west of downtown, has the island's best dinner cluster. Havensight and Yacht Haven Grande are more polished, with marina views.
Red Hook is where the evening goes late: casual bars, live music, and a lively mix of visitors and boat crews. Order a bushwacker, the USVI's frozen, boozy milkshake of a cocktail.
Where to Base Yourself on St. Thomas
The East End around Red Hook is my default recommendation: you can walk to the St. John ferry, restaurants stay open late, and resorts like the Ritz-Carlton and Secret Harbour Beach Resort put you on calm water. The south shore is the strip of resorts closest to town. Frenchman's Reef reopened in 2023 as a Westin plus an Autograph Collection property, and Bolongo Bay is still a family-run all-inclusive. Staying near Charlotte Amalie saves money and puts shopping in walking distance, but you'll drive or taxi to every beach.
When you're ready to price out the whole trip, I'll put an itinerary together for you at no extra cost. Book a vacation and I'll match the area to how you actually travel.
How to Build Your St. Thomas Week
A five-night trip breaks down cleanly:
Arrival day: settle in, then an easy beach hour at whichever one is closest to your hotel.
Boat day: half-day snorkel trip to Buck Island or Christmas Cove.
St. John day: morning ferry, Trunk Bay and Maho, dinner back in Red Hook.
Coral World and Coki Point, then Mountain Top and Drake's Seat by taxi.
Charlotte Amalie morning for duty-free shopping, lazy afternoon at Lindquist.
Ship traffic is the variable I plan around: save Magens Bay and Coki for light days, and go to St. John when four ships are in.
What to Skip on a St. Thomas Vacation
Blackbeard's Castle, once a staple of every itinerary, has been closed since the 2017 hurricanes and remained closed at my last check. Confirm before you climb the hill for it. I'd also skip renting a car for the entire week if you're based on the East End; taxis and the open-air safari buses cover most routes, driving is on the left, and parking in town tests your patience.
Timing errors are the other trap. Magens Bay and Coki Point at noon on a four-ship day are packed; the identical beaches feel private by 3:30 p.m.
When to Go to St. Thomas
Mid-December through April brings dry weather, and rates reflect the demand. May and early June offer lower prices with conditions nearly as good, which is when I send most value-focused clients. Hurricane season runs June through November, with September and October the riskiest stretch. Some restaurants close for September entirely. For any summer or fall booking, travel insurance is non-negotiable in my office.
Frequently Asked Questions About St. Thomas
Do you need a passport to visit St. Thomas?
U.S. citizens flying to St. Thomas need only a government-issued photo ID, because the USVI is a U.S. territory. Cruise passengers follow different rules depending on the itinerary. My guide on whether you need a passport for a cruise breaks down every scenario.
How many days do you need in St. Thomas?
Four to five nights is the number I recommend to clients. It covers a boat day, a St. John day, two beach days, and time in Charlotte Amalie without any rushing.
How much is the ferry from St. Thomas to St. John?
The Red Hook to Cruz Bay ferry costs $8.15 each way for adults and $1 for kids ages 2 to 11, with departures roughly every hour. The crossing takes about 20 minutes. Fares change periodically, so verify before you travel.
What is the best month to visit St. Thomas?
For guaranteed weather, February through April. For value, May. You'll get near-peak conditions at shoulder-season rates. Avoid September and October unless you're comfortable with hurricane risk and buy insurance.
Is St. Thomas safe for tourists?
The beaches, resorts, and main visitor districts see very little trouble, and I've never had a client report an incident. Use the same judgment you would in any U.S. city: keep valuables out of view and stay in populated areas after dark.
What side of the road do you drive on in St. Thomas?
The left side, a holdover from the Danish era, even though nearly every vehicle is an American model with the steering wheel on the left. Most visitors adjust within a day, but it's a real argument for taxis if you're only around for a short stay.
Final Thoughts on St. Thomas
St. Thomas rewards anyone who gives it more than a port day: real local food, an easy ferry to one of the prettiest national parks in the country, and beaches that empty out by dinnertime. Add the no-passport entry for U.S. citizens and it's one of the simplest Caribbean trips to pull off.
Still weighing a resort stay against a cruise? My Eastern Caribbean cruise guide and my Eastern versus Western Caribbean comparison will help you decide. And when you've picked your dates, I plan and book USVI vacations for clients at no added cost, meaning flights, hotel, tours, the ferry logistics, all of it. Reach out and I'll take it from here.
