A small offshore island reached via a flat 30-minute walk along the Leinster Bay trail. Widely considered some of the best snorkeling in the Caribbean — sea turtles, rays, reef fish, occasional nurse sharks.
Waterlemon Cay isn't really a beach. It's a small offshore island about 100 yards from the Leinster Bay shoreline — and the snorkeling around its perimeter is widely considered the best in the Caribbean.
The reef around Waterlemon Cay has everything snorkelers come to the Caribbean for: healthy hard and soft coral, schools of reef fish (yellowtail snapper, sergeant majors, parrotfish, blue tangs, queen angelfish), large fish like tarpon and jacks hunting the smaller schools, sea turtles, stingrays, eagle rays, and occasional nurse sharks resting under coral overhangs.
Getting to the cay requires effort. The shuttle drops you at the Leinster Bay trailhead, and you walk about 30 minutes along a flat shoreline trail to the cay's entry point. From there, you swim or kayak across the channel (about 100 yards) to begin snorkeling around the cay's perimeter. This effort filters out the cruise ship crowds — Waterlemon stays quieter than Trunk Bay despite being a more impressive snorkel.
For serious snorkelers, Waterlemon Cay is a bucket-list stop. For first-time snorkelers or families with young kids, Trunk Bay or Maho are easier picks.
Bonus history right behind the beach. There are great ruins right behind Leinster Beach, and a short hike up the hill leads to the Murphy House — an old ruin set on the hilltop with a commanding view of the bay. Most snorkelers walk right past these on the way to the cay. Worth a short detour either before or after your snorkel. Guests interested in more colonial history should also stop at the Annaberg Plantation ruins on the way back — a separate set of ruins with a full National Park Service interpretive trail, just a few minutes back down the road.
Waterlemon Cay has no on-site facilities — no concession, no rentals, no restrooms. Plan to bring everything you need for the day.
Perimeter snorkeling. The full circuit around Waterlemon Cay takes 30-45 minutes at a relaxed pace. Different sides of the cay have different conditions — the east side has more current but bigger fish; the west and south sides are calmer and have the most concentrated coral.
Sea turtle and ray viewing. The seagrass between the shoreline and the cay is grazing habitat for green sea turtles. Stingrays and eagle rays also cruise the area regularly.
The Leinster Bay trail walk. The 30-minute approach trail is flat, easy, and follows the shoreline through mangroves and salt pond areas. Bird-watchers love it. Bring water — the trail is exposed.
Kayak option. Some guests kayak across the channel from the trailhead rather than swim. Bring or rent kayaks from Cinnamon Bay concession before the trip; there are no rentals at Waterlemon.
Murphy House ruins. Right behind the Leinster Bay beach, a short hike up the hill leads to the Murphy House — an old ruin with views over the bay. Bring hiking shoes. Most snorkelers don't realize these are here.
Annaberg Plantation (separate stop on the way). Just a few minutes back down the North Shore Road, the Annaberg Sugar Mill ruins are an additional National Park interpretive site worth combining with a Waterlemon Cay visit. Different ruins, different history.
Park rules: No amplified music is allowed on any Virgin Islands National Park beach. Reef-safe sunscreen is required (chemical SPF banned in USVI). Federally protected wildlife (sea turtles, rays, nurse sharks) cannot be touched, fed, or chased — stay at least 10 feet away.
No National Park entry fee at Waterlemon Cay / Leinster Bay trailhead. Free public access.
Parking is in the Leinster Bay lot at the end of the North Shore Road, beyond Annaberg. Lot is small and fills mid-morning. Shuttle access bypasses parking and drops you right at the trailhead.
Shuttle advantage: Skip the parking question entirely. We drop you at the beach entrance and pick you up at a scheduled time.
Book a shuttle seat to Waterlemon Cay — from select Cruz Bay hotels or the ferry dock (villa pickups via private taxi). $14 per person from Cruz Bay.
It is widely ranked as one of the top snorkel destinations in the Caribbean by guidebooks, diving publications, and travel media. Marine life diversity, coral health, and the immersive perimeter snorkel make it special. Whether it is THE best is subjective, but it is genuinely world-class.
The shuttle drops you at the Leinster Bay trailhead at the end of the North Shore Road. Walk about 30 minutes along the flat shoreline trail to the cay's entry point. From there, swim or kayak about 100 yards across the channel to the cay. Plan total round-trip including snorkeling for 3-4 hours.
Yes, but with caveats. The water around the cay is generally calm, but the swim across the channel can have current. Beginners should be comfortable swimming in open water and consider a flotation vest. First-time snorkelers may be better off at Trunk Bay's easier snorkel trail.
Snorkel gear (there are no rentals at Waterlemon), water shoes for the trail and rocky entry, plenty of water for the trail walk, reef-safe sunscreen (required), a waterproof bag for valuables, and a hat for the exposed trail. There are no facilities anywhere on the route.
Occasional nurse sharks rest under coral overhangs around the cay. Nurse sharks are docile bottom-dwellers and pose no threat to snorkelers unless harassed. No reported incidents. Most snorkelers consider nurse shark sightings a highlight, not a danger.
Confirm your return pickup time with the driver in person, before they drop you off. Cell service at most St. John beaches is unreliable — you cannot count on calling or texting from the sand. Your pickup time is saved on the ticket you received when you booked; take a screenshot of it before you leave Cruz Bay. At drop-off, verbally confirm the pickup time and exact pickup location with the driver, and your driver will return at that time.
