St. Thomas Snorkeling Spots: Choosing What's Best For You

St. Thomas Snorkeling Spots: Choosing What's Best For You St. Thomas Snorkeling Spots: Choosing What's Best For You

I’ve always been a beach bum at heart. For me the perfect day has always been one at the beach with a good book, an iced tea, and a nap. St. Thomas has added to that list for me to include a bit of snorkeling. With sea turtles poking their heads up or tarpon leaping from the water just off the shore, how could I not go see what’s out there when I’m so close?

There’s nothing quite like connecting with the sea through a snorkel trip. Fish swimming around you and undersea ecosystems thriving in perfect harmony with coral, shrimp, fish, and even sea caterpillars, all as you quietly float over and observe as though you’re a part of them. Snorkeling in St. Thomas is more than an awesome excursion, it’s a moment with the sea like no other. On your visit to St. Thomas, the question is not should you snorkel, but where will you get the best snorkelling? I’m here with your islander insight to make sure your St. Thomas snorkeling trip is your best snorkel yet:



Small Islands & Cays- One of the best parts of going to the Virgin Islands is that there is a world of small islands, cays, and one of a kind sights to behold just hours or even minutes by boat from any island you have made your temporary home. Christmas Cove, is one of the top snorkeling areas as there are plenty of reefs just off of Great St. James island and many sea turtles are spotted there.  Snorkel Christmas Cove on a Half-Day Sailing Tour. Sample assorted cays off the coast and remote St. Thomas snorkeling spots on a Private All-Inclusive Full Day Sail - U.S. Virgin Islands Henley Cay is just a short kayak off the coast of St. John and offers truly amazing reef growth building up to its pure, sandy shore due to its limited encounters with humans. Scout this nearly untouched island and its thriving snorkeling display on a Henley Cay Kayaking and Snorkeling Tour. For passport holders, a Day Sail to Jost Van Dyke provides access to hidden snorkeling spots and remote cays along the way to the BVI. Explore true snorkeling gems at the Indians off of Norman Island or the Baths at Virgin Gorda or the remote destination of your choice with a St. Thomas Charter Boat Tour.

BeachesThe best St. Thomas snorkeling spots can be found at almost any beach on island, but some areas are a near sure-thing for certain marine life. Snorkeling Coki Beach, St. Thomas, guarantees you’ll swim with schools of fish, and beach vendors sell snacks for the fish, so they’ll eat right out of your hand. Secret Harbor is a quiet bay where coral growth begins the moment you step in the water. Vibrant fish, rays, and even sea turtles are often spotted, and the calm waters of the bay make it a great St. Thomas snorkeling spot for beginners. Snorkeling Sapphire Beach, one of St. Thomas’ larger beaches, provides things to see from large elkhorn coral to flapping eagle rays for hours of unique snorkeling in this great bay. The famous Magens Bay is not really known for being a beach with snorkeling spots. However on the edges of the bay, there is plenty of healthy coral and schools of fish, and tarpon, stingrays, and even sea turtles can often be found in the grassy areas. Some of my best moments with wildlife and undersea photos taken in the Caribbean Sea happened while snorkeling at Magens Bay, St. Thomas. Don’t miss spotting that awesome encounter that you have been waiting for! Rent gear or bring your own and hit all of these world-class snorkeling spots in one day on a St. Thomas Beach Hopping Private Tour or sample one of these beaches and add in some island sights on a St. Thomas Sightseeing and Beach TourSt. John is also home to great snorkeling locations in its National Park Service waters such as Trunk Bay, Cinnamon Bay, and Maho Bay.
