What You Can Expect

St Thomas Mangrove Lagoon Kayak and Snorkel Tour

Snorkel in St Thomas!

The southern coast of St. Thomas is home to the attractive and protected Mangrove Lagoon Wildlife Sanctuary and Marine Preserve. An area of exceptional natural beauty, it embraces islands, rocky cliffs, sea grass beds, salt ponds and panoramic ridge lines. These areas preserve a rich habitat for coral reef fish and invertebrates and are home to nesting egrets, pelicans, blue herons and terns.

Led by your nature guide, you’ll travel through the protected Inner Mangrove Lagoon Marine Reserve to Long Point at Patricia Cay. Here, you'll kayak among the many small islands of the mangrove lagoon.

As you paddle through the clear blue water, keep an eye out for sting rays and spotted rays, as they often glide right beneath you. Occasionally they'll jump in the air and put on a show!

Next, it's time to don a mask and snorkel to explore the coral-fringed mangroves of the sanctuary. Don't worry if this is your first time snorkeling. The professional guides offer snorkeling instruction, point out the marine life and discuss the diverse mangrove ecosystem. Following the snorkel, you'll enjoy a leisurely 20-minute paddle back to the marina.

If you select the hiking option, you'll hike the pristine deserted island of Cas Cay. An important part of the Virgin Islands Park System, Cas Cay is a 15-acre wildlife preserve for white-cheeked pintail ducks, red-billed and white-tailed tropic birds, brown pelicans, oyster catchers, roseate terns, egrets, herons and sandpipers. Enjoy many breathtaking views of tidal pools and the island's unique blowhole from coral and shell beaches at the base of volcanic cliffs.

The whole tour was excellent--the locations gave us a private and natural experience and the locations for kayaking and then snorkeling were picturesque. The guides were awesome especially Jai who was so upbeat, welcoming hello my beautiful people! and so proud of his island and it's beauty. He spent extra time with the kids in the water and on the crab island where an area of the ground and even trees were covered in red-claw hermit crabs, explaining the creatures we were seeing. We really appreciated his hospitality, do this tour!

I booked this tour not wanting to go, because I have a fear of the ocean and sea creatures. But everyone in my group wanted to do it so I followed along. And I'm SO SO SO glad I did! The kayake adventure is thru the mangroves and does feel like your in the ocean at all, rather a lake or stream.

Our tour guide Nathan was great and very informative about the local plants on the hike and the aquatic life. We saw many species of fish some invertebrates too.
The only thing I didn't like is being an experienced snorkeler I did not like being told to leave my fins behind.

This was a great experience. The staff all took good care of me, which was much appreciated as I am a senior single traveler. I was paired in a kayak by a delightful young lady who was a new member of the guide staff. She ensured that we could keep up with the rest of the group in a quite lengthy passage from the dock to the snorkeling site. The lead guide was very informative at the several sites along the way and the snorkeling was good near the entrance to the lagoon. The experience of being surrounded by thousands of baby fish around the mangrove roots was unique.

This was my favorite part of my trip to St. Thomas! The mangrove lagoon was beautiful to kayak through as we made our way to Cas Cay. We walked/hiked to a blow hole with tide pools and our guides pointed out marine life. Afterwards, we snorkeled and saw tons of different fish and even a sting ray. Overall, this was a really great experience and the guides were very knowledgeable and friendly. Definitely something I would try again on my next visit to the island.

I wanted to do this again every day I was on the island. Laura Lee was knowledgeable, funny, and an all around delightful tour guide. Our entire group of seven had a great time kayaking and snorkeling with the fish and jellies. Don't miss this tour!
