St. Thomas Excursions

Booking Through the Ship or Booking Yourself

Royal Caribbean, Carnival, Princess and the rest all sell St. Thomas excursions through their own shore-excursion desks. They are not running the boats. In almost every case they are reselling the same local operators you can book directly, with a margin on top and the ship's guarantee underneath.

That guarantee is the whole trade. Book through the ship and if the excursion runs late, the ship waits. Book independently and you carry that risk yourself, which is why the 90-minute buffer matters.

Book independently and you get a wider choice, lower prices and smaller groups. Ship excursions fill big boats because they have to move hundreds of passengers; the same reef trip sold independently often runs with a dozen people. Several independent operators also refund fully if your ship never ports, which removes most of the risk that pushes people toward the ship's desk in the first place.

The honest split: book through the ship if your port stop is short, your schedule is tight, or the excursion goes far from the pier. Book yourself for anything close, cheap or flexible. A snorkel trip 20 minutes from the dock does not need the ship's insurance policy.

Which Pier You Dock At

Two docks, and the difference changes your morning.

Most ships tie up at the West Indian Company dock in Havensight, on the east side of Charlotte Amalie harbour. It has a shopping mall at the gate, taxis lined up outside, and the shortest run into town.

Others use Crown Bay, west of the harbour in Subbase. It is quieter, smaller and further from everything.

Check your itinerary before you plan, because a beach that is 25 minutes from Havensight may be 40 from Crown Bay, and taxi fares are quoted per person rather than per car.

Is St. Thomas Walkable from the Cruise Port?

From Havensight, yes, if you like walking. Downtown Charlotte Amalie sits about 1.5 miles away, roughly a 30-minute walk along the waterfront. It is flat, it is hot, and there is a footpath most of the way.

From Crown Bay, not really. Downtown is about 2 miles off and the walk takes around 40 minutes along a road that was not built for pedestrians. Take the taxi.

Either way, a shared taxi into town is regulated at roughly $5 to $6 per person and takes 5 to 10 minutes from Havensight. Given the heat, most people walk one direction and ride the other.

Walking is worth it for the town itself: Fort Christian, the 99 Steps, Blackbeard's Castle and the duty-free shopping on Main Street all sit within a few blocks. It is not worth it as a way to reach a beach. No beach on St. Thomas is walkable from either pier.

What St. Thomas Excursions Cost

The full spread of bookable trips on this island runs $64 to $1,495. That top figure is a whole-boat private charter for a group rather than a per-person seat.

Where most people land:

Under $100 buys a 2-hour guided turtle snorkel at Brewers Bay at $89, a 3-hour mangrove kayak and snorkel at $99, or a shark encounter with park admission at $64.

Between $100 and $160 covers the bulk of the market: a 75-minute SNUBA session at $102, a 3-hour catamaran sail and snorkel at $109, the underwater scooter at $131, a two-reef dive-boat trip at $129, a 4-hour power catamaran at $150, and a 5-hour all-inclusive sailing day with breakfast, lunch and open bar at $157.

Above that you are into specialist and private territory: a two-tank reef dive at $189 for certified divers, a private island tour by jeep from $199, and whole-boat charters at $1,495.

Budget for the extras. Taxis run $9 to $15 per person each way to the north-shore beaches, photo packages cost around $50, and lunch off the boat averages $10 to $15.

Snorkel and Sail Excursions

The default St. Thomas excursion, and the one the island does best.

The scheduled catamarans sail to Turtle Cove off Buck Island, which you cannot reach by swimming from any beach. That is the entire argument for paying for a boat rather than taking a taxi to a beach with a mask. A catamaran sail and snorkel books at $109 for 3 hours; the VI Cat runs the same water on a 54-foot boat licensed for 80 guests.

Smaller dive boats sit between the catamarans and a private charter. A two-reef trip carries a handful of snorkelers for $129 and reaches sites the big boats skip.

At the top, a 5-hour all-inclusive sailing day at $157 includes breakfast, lunch and an open bar, which works out cheaper than buying lunch and drinks separately in town.

What separates a good trip from a bad one here is group size, not destination. Everyone visits the same handful of reefs. Our St. Thomas snorkeling tours compared page ranks them on price, rating and group size.

Underwater Without Learning to Dive

Two St. Thomas excursions let you breathe underwater with no certification, and they suit different people.

SNUBA at Coki Point costs $102 for 75 minutes. You breathe from an air line running to a raft on the surface, drop 15 to 20 feet, and go in groups of four. It is the closest thing to scuba without the course.

The BOSS underwater scooter costs $131 for a 3.5-hour trip from a 60-foot dive yacht. You sit on a powered scooter with a clear air dome over your head and drive along the reef. Your head never goes underwater, which means non-swimmers can do it.

The limits are stricter than people expect: maximum weight 350 lb, minimum age 10, minimum height 4 feet. It is also non-refundable, which is unusual on this island where most trips cancel free.

If someone in your group has sat out every water excursion because they cannot swim, the scooter is the one that works.

Beach Days on Your Own

The cheapest good day on St. Thomas involves no excursion at all.

Coki Point charges no entrance fee and puts reef a few kicks from the sand. A taxi runs $9 to $15 per person each way and the drive takes 20 to 30 minutes. Bring a mask and the day costs you the fare. Vendors on the beach rent gear, chairs and umbrellas if you arrive empty-handed.

Sapphire Beach on the east end parks for free and lays its reef along a rocky ledge on the right-hand side, with fan coral about 150 yards out for confident swimmers. Fewer cruise passengers make it there.

Brewers Bay, near the airport, is the island's most reliable place to see green turtles from shore, because they graze the seagrass through the day.

Magens Bay is the postcard: a mile-long curve of sand and the beach everyone photographs. The snorkelling is the weakest of the four. Go for the scenery.

This is what people mean by St. Thomas excursions on your own, and for snorkelling specifically it is a genuinely competitive option rather than a budget compromise.

Island Tours, Jeeps and Mountain Top

For anyone who does not want to get wet, or a second port day.

A private island tour with a local driver-guide starts at $199 for 2 hours and runs to 6, covering Mountain Top for the view over Magens Bay, Charlotte Amalie's viewpoints and Drake's Seat. Mountain Top is the highest point most visitors reach and the banana daiquiri there is an island institution.

Open-air jeep tours cover similar ground with more of the interior. Several independent operators run them alongside their water trips, which is covered on our page about the St. Thomas adventure operators.

Shared island tours by open-air safari bus are the cheap version and the one most ships sell. You see the same viewpoints on somebody else's schedule.

Kayaking and the Mangroves

The Cas Cay mangrove kayak, hike and snorkel runs $99 for 3 hours and is the most different thing on this list. You paddle through mangrove channels in the marine sanctuary on the east end, land on Cas Cay, walk to a blowhole, and snorkel off the cay.

It suits families and anyone bored of boat decks. The water is protected, so it works on days when the north shore is choppy.

There is also a guided LED night kayak, which paddles clear-bottomed boats lit from underneath after dark. It is a novelty rather than a wildlife trip, and it is genuinely good with children.

Scuba Diving

Certified divers can book a two-tank reef dive at $189. St. Thomas dive sites include reef walls, wrecks and the drop-offs past the shore points, and visibility holds up year-round.

Uncertified divers who want more than snorkelling should look at SNUBA at $102 rather than a resort course, unless you have a full day to give up.

A note on ear pressure: SNUBA and scuba both require equalising. The underwater scooter does not, because your head stays in air the whole time. That distinction matters more than most excursion listings admit.

St. Thomas Excursions for Kids

Coral World Ocean Park is the reliable one. Five acres of aquariums, nature trails and outdoor pools, plus animal encounters that book separately: a shark encounter with admission at $64, a sea lion encounter at $119 and a swim with dolphins at $183.

Beyond the park: the mangrove kayak at $99 works from about eight years upward, the beach at Coki Point costs nothing and has shallow water and food nearby, and the LED night kayak is a hit with older children.

What does not work with young children: the underwater scooter, which sets a minimum age of 10 and a minimum height of 4 feet, and full-day sailing trips, which are long.

Day Trips off the Island

St. John sits a short crossing east and has the better beaches of the two islands. Several catamaran trips cross for a day of snorkelling on both, and the national park beaches there are the ones people remember.

The British Virgin Islands need a passport and a scheduled ferry rather than an excursion boat. Road Town Fast Ferry charges $35 one way for an adult from Charlotte Amalie, and fares across the three operators run $25 to $65. Add a $10 port fee, a $10 BVI environmental tax on entry and a $20 departure tax, and the crossing costs more than it first looks.

Cruise passengers should think hard before attempting the BVI on a port day. Immigration on both ends eats the margin, and missing the return ferry means missing the ship.

What Not to Miss on St. Thomas

If you only do one thing, get in the water. This island's argument over every other Caribbean stop is that reef sits within a few kicks of the sand at multiple beaches, and the water holds green turtles, hawksbills, spotted eagle rays, parrotfish and nurse sharks.

The short list, in order of how often people say they were glad they did it:

Snorkelling at Coki Point or on a boat trip to Turtle Cove. Mountain Top for the view down over Magens Bay, which is the photograph everyone comes home with. Magens Bay itself for an hour of sand. Historic Charlotte Amalie if you are walking from Havensight anyway.

What you can skip: the duty-free shopping, unless you actually want jewellery. It absorbs a whole port day and it is the same in every Caribbean port.

The Best Excursion by How Many Hours You Have

There is no single best excursion in St. Thomas. There is a best one for the hours you hold.

Three hours or less: SNUBA at Coki Point at $102 for 75 minutes, or a taxi to Coki and snorkel from the beach for the price of the fare. Both leave margin for the return.

Four to five hours: the 3-hour catamaran sail and snorkel at $109, the 3.5-hour underwater scooter at $131, or the Cas Cay mangrove kayak at $99. This is the sweet spot for a standard port day.

Six hours or more: the 5-hour all-inclusive sailing day at $157, a two-tank dive at $189, or a St. John crossing.

A full day on the island rather than a ship: a private charter at $1,495 for the group, or a private island tour from $199 combined with a beach afternoon.

Timing, Taxis and All-Aboard

The single rule that matters: start back at least 90 minutes before all-aboard. Independent excursions do not hold the ship.

Taxis are shared, open-air and regulated, quoted per person rather than per car. About $5 to $6 into town from Havensight, $9 to $15 per person each way to the north-shore beaches. They line up outside the terminal whenever ships are in, and they fill before they leave, so a solo traveller may wait for other passengers.

High season runs December through April, when several ships call at once and the beaches and taxi queues both stretch. Water temperature sits between 78°F in February and 86°F in August, so nobody needs a wetsuit at any point in the year. April to June brings the calmest seas and the clearest water, which is the best snorkelling of the year and outside the busiest months.

One last thing worth knowing: most independent operators here cancel free, and several refund in full if your ship never ports. Check that before you assume the ship's desk is the safer booking.
