While visiting Trunk Bay, i snorkeled the underwater trail. It is an easy swim and is a good place to start a beginner. There are usually a lot of people snorkeling, so the bottom does not have a grand spectrum of sights, but there are enough for a novice to get excited about snorkeling. The beach is grand and with...

The self guided underwater snorkel trail is not the best snorkeling on the island, but its a good first spot to check out. First of all, Trunk Bay beach is among the best on St John. The underwater trail itself gives the snorkeler maybe a dozen underwater stone markers to follow which have written explanations on them of what you... More

Our children loved the underwater trail. It was accessible, even for our 5 year old. They enjoyed the information signs (though I often had to dive down to read them). The reefs are in good condition because the lifeguards patrol them thoroughly to ensure no one damages them. Busy beach, but worth braving the crowds if you want to introduce... More

I mean how many times have you followed an underwater trail? Seriously. The water is the perfect temperature. You're snorkeling anyway. Follow the trail and read the signs on the rocks.

It's really sad to see that the snorkelers have killed the coral reef around the little island, except for a small patch at the very end (red/pink buoy)

Snorkeling the NPS Underwater Trail was fun, interesting & relatively easy for beginning snorkelers. Rental gear is nearby & the trail is easily accessed from the beach.

As far as I know, this is the only marked underwater trail in the world and has a number of interpretive signs underwater describing what one is seeing as they snorkel between three buoys. The trail is located at the eastern end of the spectacular, world class Trunk Bay Beach between the shore and the small island of Trunk Cay... More

At the national park, there is one beach that allows cabin rentals for folks with overnight stay. Let me help you out with this decision. It’s not very nice and is almost comparable to being thrust into the bad camping adventure in a small shack. I would highly recommend that for you sleeping in one of the hotels or rental... More

Beautiful beach. Fun & safe snorkel. Lifeguards present on the beach and usually in the water on paddle boards. The coral on the reef has seen better days but there were several beautiful fish. Overall it was fun.

Go for the beach which is lovely. As noted by others, the underwater trail is underwhelming and used to be much larger and better maintained
