Water Island St Thomas: A Guide

Water Island is the fourth major island in the U.S. Virgin Islands, located just south of St. Thomas. The smallest of the four main islands, Water Island still packs a ton of vacation fun into their shores. Known for their laid-back atmosphere, Water Island is one of the least populated and most relaxed of the USVI. Here’s how you can spend a magical vacation in St. Thomas with a trip to Water Island!

Accessing Water Island St Thomas

Despite its proximity to St. Thomas (just over 3 miles), Water Island is relatively secluded. The island is mainly accessed via a 10 minute ferry ride. The island’s small size makes it easy to explore on foot, which most visitors do – though some go for the added convenience of renting a golf cart from a local provider. 

The Water Island Ferry leaves from Crown Bay Marina, where you’ll pay your fare ($15 adults round trip, $5 kids round trip) with cash only and hop aboard for a 10 minute ride across the water. The ferry runs regularly throughout the day, with variations during off-season and late at night. Check the ferry schedule to plan your itinerary!

You’ll return to St. Thomas on the same ferry, this time leaving from Philips Landing on Water Island.

History of Water Island St Thomas USVI

Once owned by the Danish government and used for a wide range of purposes like a quarantine station, World War II submarine base, and a sugar plantation, Water Island has a rich and interesting history. Most of the island is still owned by private individuals after a series of sales in the late 1990s, keeping Water Island the non-commercial paradise that is a welcome refuge from more modernized vacation spots.

If you want to explore Water Island’s history, a great place to check out is Fort Segarra. Guests can walk through underground rooms, inside tunnels, and see weapon emplacements. Fort Segarra is not set up as a museum or park, and caution should be used when exploring. Be respectful of the area’s history, and do not remove or disturb artifacts. Locals recommend a flashlight and close-toed shoes.

Hiking on Water Island

Honeymoon Beach from Philips Landing, 20 minute loop

Limestone Beach from Philips Landing, about an hour there and back

Fort Segarra from Philips Landing, 1.5 miles one way

Carolina Point Plantation from Philips Landing, 1.5 miles one way

Hiking to Limestone Beach? Many visitors and locals visit Limestone Beach for snorkeling, as the reef that runs parallel to the beach provides a place for marine life to thrive and makes for great exploring. The water beyond the reef is deep and can be rough, so passing over it isn’t recommended. Stay on the beach side and enjoy the calm waters!

Snorkeling and Diving Water Island

The water around the island is home to dozens of species of marine life, including some stunning coral reefs. Water Island is known for tranquil beaches, and that translates into tranquil waters that are perfect for snorkeling and diving. Limestone Bay is one of the most popular places to dive and snorkel on Water Island, offering a secluded area with calm water.

Want to explore further? Plan a scuba expedition to Supermarket Reef, a coral reef off Water Island’s coast that grew to feature “aisles” where sea turtles, many species of fish, eels, and more make their homes. Don’t forget water shoes – Supermarket Reef is a rocky spot, which is part of why the marine life loves it so much!
