Best Snorkeling in the USVI: A Captain's Ranked List of 9 Spots

After ten years and hundreds of snorkel stops across the USVI, I get asked the 'best snorkeling' question more than any other. The honest answer is that the best snorkeling depends on what you want — the most fish, the easiest entry, the most reliable turtles, the healthiest coral — and on the day's conditions. This is the ranked list I'd give a friend planning their first trip, with the caveat that all nine of these spots are genuinely world-class. The ranking is a tie-breaker, not a judgment.

1. Waterlemon Cay (Leinster Bay, St. John)

The overall winner. A small rocky islet at the mouth of Leinster Bay on St. John's north shore, with the healthiest coral and densest fish life in the territory. The swim from the beach is a 20-minute crossing of seagrass channel that's full of green sea turtles, spotted eagle rays, and conch. The reef around the cay itself drops from shallow seagrass to a coral slope at 8–15 feet, thick with elkhorn coral, sea fans, parrotfish, blue tangs, and the occasional reef shark. Best in calm morning conditions. Not for beginners — there are no lifeguards, no marked trails, and the swim is substantial.

2. Trunk Bay underwater trail (St. John)

The most famous snorkel in the USVI, and the best for beginners. The underwater trail is a marked loop in the shallow water just off the beach, with submerged plaques identifying the coral and fish you swim past. The reef has suffered from heavy use and bleaching over the years, but the experience is still excellent for first-time snorkelers — calm, shallow, supervised, structured. Go early (before 9:30 a.m.) for the best conditions and to beat the cruise excursion crowds. The mooring ball is required for boats; the ashore fee is $5 per person.

3. Maho Bay (St. John)

The most reliable place in the USVI to snorkel with green sea turtles. The seagrass meadows in Maho Bay are a primary feeding area, and turtles surface every 5–7 minutes throughout the day. The bay is calm, shallow, and easy to enter from the beach. The coral is modest — the show here is the wildlife, not the reef — but the turtle density is the highest in the park. Anchoring is restricted to designated moorings (anchoring on seagrass is prohibited and damages turtle habitat). Best at dawn or late afternoon when the turtles are most active and the bay is quietest.

4. Honeymoon Beach (Water Island, off St. Thomas)

A small crescent beach on Water Island, just off Charlotte Amalie. The water is calm and shallow, the reef starts about 30 feet from shore, and the fish life is excellent — parrotfish, sergeant majors, trumpetfish, the occasional turtle. There's a small beach bar (Dinghy's), kayak rentals, and a sandy entry that's perfect for kids and nervous snorkelers. Accessible by water taxi from Crown Bay or by dinghy from a boat anchored in the cove. One of the few St. Thomas-area snorkels that competes with the St. John bays.

5. Buck Island Reef (off St. Thomas)

Not to be confused with the more famous Buck Island Reef National Monument off St. Croix. The St. Thomas Buck Island has a shallow protected snorkel area on its west side with good coral and reliable fish life, and is a common stop on day-charter itineraries from the Red Hook side. The mooring field can get crowded with day-trip boats in peak season. Best in the morning before the boat traffic builds.

6. Christmas Cove (Great St. James)

Between St. Thomas and St. John, Christmas Cove is the home of the Pizza Pi floating pizzeria and an excellent snorkel reef on the cove's south side. The reef is shallow, accessible, and has the easy-going quality of a spot you can swim from a moored boat without much planning. Fish life is good — parrotfish, blue tangs, sergeant majors — and the social scene around Pizza Pi makes it a fun lunch stop. Not the wildest snorkel, but one of the most enjoyable.

7. Salt Pond Bay (St. John, south shore)

The wild card. Salt Pond is on St. John's exposed south shore, accessible by a short hike from the road or by boat in settled weather. The Drunk Bay snorkel just east of Salt Pond has dramatic underwater topography — rock arches, swim-throughs, deep coral heads — and a remote, untouched feel. Conditions can be rough; this is a calm-day-only snorkel. When it's on, it's one of the most memorable swims in the USVI.

8. Cinnamon Bay (St. John)

The longest beach on St. John, with a good reef at the east end near Cinnamon Cay. The reef is healthy, the swim is moderate, and the bay is far less crowded than Trunk Bay despite being a similar quality experience. Easy entry from the beach. Sea turtles are common in the seagrass channels. A great backup if Trunk Bay is full and you want a comparable beach-snorkel combination.

9. Hawksnest Bay (St. John)

The closest of the big north-shore beaches to Cruz Bay, with a decent shallow reef on the west side. The snorkeling isn't as dramatic as the higher-ranked spots, but the convenience is unmatched — easy beach access, calm water, lifeguard on duty, good for families with small children who can't yet handle Trunk Bay's underwater trail. Often overlooked, which means it's quieter than Trunk Bay even in peak season.

The Captain's take

If you can only do three, do Waterlemon Cay, Trunk Bay, and Maho Bay — in that order, in a single day on the north shore of St. John. The fourth I'd add is Honeymoon Beach on Water Island, because it's a perfect lunch-and-swim stop on the way between St. Thomas and St. John and gives you a different flavor of the underwater landscape. The thing nobody tells you is that the best snorkeling experiences in the USVI aren't really about which reef is healthiest — they're about access and timing. The reefs that get the dawn light, before the trade winds and the day-trip boats arrive, are the reefs that look the way you imagined. That's the unfair advantage of being on a boat. You're in the water at 7:30 a.m., not 11:00 a.m., and the difference is the trip.

Building a snorkel-focused charter week

A week-long catamaran charter focused on the best snorkeling in the USVI looks something like this: day one, settle in at Honeymoon Beach for an easy first swim; day two, sail to St. John's north shore and anchor in Francis Bay for Waterlemon Cay at dawn; day three, drop down to Maho Bay for the turtle morning, then Trunk Bay before the crowds; day four, around to Salt Pond on the south shore if conditions allow; day five, back across to Christmas Cove and Pizza Pi; day six, the WIT Shoal wreck if you've got an experienced group; day seven, a quiet morning anywhere you want to revisit. Seven different snorkels, each one different from the last, all impossible to string together as a land-based trip.
