Sea Turtle Species & Best Months in St. Thomas

Species	January–March	April–June	July–September	October–December	Likelihood
Green Sea Turtle	Common	Common	Common	Common	Near-guaranteed
Hawksbill Turtle	Regular	Regular	Regular	Regular	Regular

Green turtles are the stars here, grazing the seagrass at Brewers Bay and Turtle Cove; adults reach 300 to 400 pounds. Hawksbills, smaller and critically endangered, feed on sponges around the reefs and wrecks off Buck Island and Water Island. Both are protected under the US Endangered Species Act, so touching, chasing or feeding them is a federal offense. Keep 6 to 10 feet of distance and let the turtle set the pace.

What to Expect on the Day

Check in at the marina or beach

Boats leave from Yacht Haven Grande, Saga Haven Marina, Red Hook or the Westin at Frenchman's Reef; the shore snorkel meets right on Brewers Bay beach. Arrive 15 to 30 minutes early for gear fitting.

Wear your swimsuit under your clothes and allow extra time for island taxi traffic.

Short ride to the turtle grounds

Buck Island and Water Island sit just south of the harbor, so most boats reach the first snorkel spot in 15 to 30 minutes.

Guided snorkel with the turtles

Your guide gets in the water with you, points out green turtles over the seagrass, and hands out pool noodles to anyone who wants extra float.

Second stop: wreck, reef or beach

Most trips add a second act: a shipwreck snorkel, a second reef, or beach time at Honeymoon Beach on Water Island.

Snacks and the ride home

Back on board there are snacks, soda and, on most boats, rum punch or an open bar for the cruise back.

No turtle sighted? Sightings are close to certain: Turtle Cove and Brewers Bay hold resident green turtles year-round, and one operator, the 6-guest kayak-and-snorkel trip, states a turtle guarantee on every tour. Go in the morning for the calmest, clearest water, and treat a close pass as a bonus rather than something to chase.

Sea Turtle Behaviors to Watch For

Grazing the Seagrass

Green turtles crop the seagrass beds of Brewers Bay and Turtle Cove like slow lawnmowers, surfacing every few minutes. This is the sight most snorkelers remember.

On most swims

Cruising the Wrecks

Hawksbills pick sponges off the coral that has grown over the wrecks near Buck Island, including the shipwreck several boat tours visit when conditions allow.

At the wrecks

Surfacing to Breathe

Turtles rise for air every few minutes when active. Give them a clear path up and never hover directly above one.

On every snorkel

What to Bring (and What to Leave at Home)

✓ Bring

Reef-safe mineral sunscreen (oxybenzone sunscreens are banned in the USVI)
Rash guard or swim shirt for sun protection
Towel and a change of clothes
Waterproof phone case or GoPro
Cash for crew tips (20% is customary on the island)
Your booking voucher (printed or on your phone)

✗ Leave at home

Oxybenzone sunscreen (illegal to use in the US Virgin Islands)
Anything you would touch or feed a turtle with
Single-use plastics
Valuables you can't afford to get wet

Seasickness tip: Most trips stay in the sheltered water between St. Thomas and Water Island, so seasickness is rare. The 6-hour St. John sail crosses open Pillsbury Sound; if you are prone, take a tablet the night before and skip the rum punch until after the snorkel.

Where Tours Depart From

Port / Area	Details	Best for
Yacht Haven Grande (Charlotte Amalie)	Next to the WICO cruise dock, so cruise passengers can walk to the boat.	Cruise-ship days
Red Hook & Saga Haven (east end)	The St. John sail leaves American Yacht Harbor in Red Hook; the two-spot boat trip leaves nearby Saga Haven Marina.	East-end stays
Westin at Frenchman's Reef	The Buck Island sail departs the resort's watersports dock; parking is $10.	Resort guests
Brewers Bay & Lindbergh Bay beaches	The shore snorkel meets on Brewers Bay beach; the kayak trip picks up at Emerald Beach Resort on Lindbergh Bay.	Shore-based trips

Taxis reach every departure point, but reviewers warn that traffic from the cruise docks can be slow, so leave more time than the map suggests. Brewers Bay sits beside the airport runway, about 20 minutes from the WICO dock; Red Hook on the east end can take 30 to 45 minutes in traffic.

Best Shore Spots to See Turtles in St. Thomas

These shore and reef spots let snorkelers and beachgoers find sea turtles in St. Thomas without a boat. Keep your distance and never touch a resting turtle.

Brewers Bay

Main turtle bay

A wide, protected bay beside the airport runway where green turtles graze shallow seagrass beds. Calm water and easy sand entry make it the island's most reliable shore snorkel.

💡 Go in the morning before the wind ripples the bay. The $79 guided tour meets by the beach stairs near the bath house.

Lindbergh Bay

Calm & easy

A sheltered beach near the airport hotels with seagrass patches that draw feeding turtles. The kayak-and-snorkel tour uses it as home base.

💡 Stick to the middle of the bay over the grass beds; the edges are mostly sand.

Secret Harbour

East end

A calm east-end cove with rocky points on both sides where turtles, rays and squid feed. Good visibility on most mornings.

💡 Snorkel the left point at mid-morning; the beach bar makes an easy base for non-swimmers.

Sapphire Beach

Reef + views

An east-end beach with a reef along its right side and St. John on the horizon. Turtles pass through the grass between reef patches.

💡 Enter at the right end near the rocks and work along the reef line.

FAQ: Swimming With Turtles in St. Thomas

What is the price of swimming with turtles in St. Thomas?

⌄

Tours start at $79 for a 2-hour guided shore snorkel at Brewers Bay. Half-day boat trips to Buck Island and Water Island run $109 to $159, and the 6-hour St. John sail with Pizza Pi lunch is $295. Most boat tours include free cancellation up to 24 hours before; the two-spot boat trip and the Pizza Pi sail are non-refundable, so book those once plans are firm.

Where is the best place to swim with turtles in St. Thomas?

⌄

Turtle Cove at Buck Island National Wildlife Refuge is the classic boat stop, with resident green turtles over the seagrass. From shore, Brewers Bay is the most reliable spot on the island. Across Pillsbury Sound, Maho Bay on St. John is famous for turtles and is the second stop on the 6-hour sail.

Are turtle sightings guaranteed?

⌄

Close to it. Green turtles live on these seagrass beds year-round, and recent reviews across all six tours report sightings on nearly every trip. The 6-guest kayak-and-snorkel tour goes further and states a turtle guarantee on every departure.

What time of day is best for turtle snorkeling?

⌄

Morning. The bays are calmest and clearest before the trade winds build after midday, and the turtles feed steadily through the morning hours. Most boats offer a 9 or 10 am start; afternoon trips still see turtles but can meet choppier water.

Can beginners and kids swim with turtles here?

⌄

Yes. The Brewers Bay shore snorkel is the easiest start: you walk in from the sand into shallow, calm water with a guide beside you. Boat tours hand out pool noodles and flotation vests. Minimum ages vary from 5 to 6 years depending on the tour, and all operators require that guests can swim.

Can I see turtles from shore for free?

⌄

You can. Brewers Bay is a public beach, and confident snorkelers with their own gear regularly find turtles over the seagrass. The guided version adds gear, a spotter who knows where the turtles feed, and help for anyone new to snorkeling.

Which turtle tour should cruise passengers pick?

⌄

The luxury catamaran leaves Yacht Haven Grande, next to the WICO cruise dock, so there is no taxi gamble and crews are used to ship schedules. If your ship docks at Crown Bay, Brewers Bay is a short taxi ride away for the shore snorkel. Leave buffer time either way; island traffic is slow at midday.
