Trail is at Trunk Bay beach. Snorkeling trail is good with markers in the water to follow. Can't get lost and easy to navigate. Large school of silversides with tarpon and bar jacks looking for a free meal. Take a Go Pro if you have...More

There is better snorkeling around. We did a private charter and it's hard to appreciate this site after all we did. Worth doing if you have your own snorkel & mask, but I wouldn't rent for this site. Just sit and enjoy the beach.

This underwater trail has signs explaining about fish and coral. Easy to follow. However, more fish can be found closer to the island. Trunk Bay is beautiful.

Perfect day of snorkeling for the novice. An easy trail wherein you can't really get in trouble. There is a lifeguard shack which had 2 lifeguards watching the "trail" at all times. Great place for kids to start their snorkeling experience.

Snorkeling and the beach are always fun but if you're looking for good snorkeling, go elsewhere around St. John. There are multiple other stops. The beach is lovely and there are services available so it's a great place for a day at the beach.

Spent a day here off a cruise ship. I had not been snorkeling for over twenty years but warm currents and beautiful scenery saw me spend an hour exploring the marked trail.

Very cool trail, pretty easy to navigate, currents weren't too bad. It was a little over cast so water wasn't as clear as it usually is, but still a must see.

In theory this sounds great. The day we went it was over crowded with people snorkeling and I'm sure that influenced the sea-life. It was cute to read the signs underwater of what was supposed to inhabit the area near the plaques. Only saw a...More

No boats. You can rent gear and get a brief overview of the trail from the beach. Once you have your gear head on out. No boat needed. You can snorkel from the shore to the end of the island and back. It's a long trail.

Thirty feet in the deepest spot at the end of rock outcropping.
