Backpacking in Waterlemon Cay
👌 Worth visitingbeach ranked #9
By Johan Kruseman 🇳🇱 | Updated October 22, 2026

Waterlemon Cay is a small rocky island about 100 yards offshore, ringed by seagrass and coral, and the usual way to reach it is to swim out from the beach at the end of the Leinster Bay trail. The beach lies on the north shore of St. John, in the United States Virgin Islands, inside Virgin Islands National Park. Snorkeling is the reason to come: turtles graze the grass beds, and rays and reef fish gather around the cay’s edge. The sand itself is narrow and rocky, so it is not a lounging beach. Expect a hot, shadeless walk of roughly 20 minutes from the road, no food or lodging at the trailhead, and a current that picks up beyond the island. Worth the effort for confident snorkelers. Skip it if you want sunbeds or easy entry.

✨ Why go?
Ranked #9 beach in United States Virgin IslandsWhy Waterlemon Cay should be on your travel list

Backpackers stop at Waterlemon Cay beach because the snorkeling here is among the best on St. John, and you reach it on foot rather than on a boat tour. The walk starts at the Annaberg Sugar Mill ruins and follows the shoreline of Leinster Bay, so the day has a bit of history built in before you get wet. There is no entry fee here, which keeps things easy on a tight budget.

The real draw is the loop around the cay. On the sheltered side, turtles and spotted eagle rays are regular sights over the seagrass, and the coral wall on the outer edge holds schools of fish. It also works as a calm break for anyone traveling the north shore, since the crowds stay thin compared with Trunk Bay and Cinnamon Bay. Bring your own gear and water, because nothing is sold at the sand.

💡 HighlightsPlaces and moments you shouldn't skip

  1. Snorkeling around Waterlemon Cay: the main event. Swim the short channel to the island and circle it. The inner side is calm and shallow, while the outer edge has more coral and a stronger current, so stay close to the rocks.
  2. Turtle and ray watching over the seagrass: green turtles feed in the grass beds between the beach and the cay, and spotted eagle rays glide through the same stretch. Float quietly and keep your distance.
  3. The Leinster Bay Trail: a flat, exposed walk of about 20 minutes along the bay, passing salt-crusted shoreline and small coves. Wear sturdy sandals and carry water.
  4. Annaberg Sugar Mill ruins: at the start of the trail, the stone mill, boiling house and slave quarters remain from the plantation era. Entry to the site is covered by the park, and an hour is plenty.
  5. Starfish

  5. Starfish hunting in the shallows: the sandy and grassy flats near the beach often hold large red cushion sea stars. Look but do not lift them from the water.
Do the Annaberg ruins first, early in the morning, so you walk the trail before the heat builds and reach the water while the light is clear for snorkeling.

🌤️ When to go?Weather, crowds, and seasonal trade-offs

  • Dry Season (December to April): Calm seas and the clearest water make this the best window for the snorkel out to the cay. Daytime highs run 28 to 30°C (82 to 86°F), nights 22 to 24°C (72 to 75°F), with about 11 to 12 hours of daylight.
  • Hurricane Season (June to November): Peak risk falls from August to October. Expect heat of 30 to 32°C (86 to 90°F), swells after storms, cloudy water and some closures. Lodging is cheaper, and the crowds thin out.
  • Holiday Weeks: Christmas through New Year and spring break fill rooms, and rates in nearby St. John rise by roughly 30 to 50 percent.
  • Shoulder Months (May and early December): Quiet trailheads, decent visibility and softer prices.
Go early in the morning, when the water is flat and the Leinster Bay Trail is still cool.

🛏️ Where to stay?How to pick the right area

Coral Bay is the best base for Waterlemon Cay, sitting about 10 to 15 minutes by car from the Annaberg trailhead where the walk to the beach begins. It is the quiet, local side of St. John, with a few bars, a small market and rustic guesthouses, villas and campsite-style lodging. Rooms are limited, and budget options run roughly US$100 to 200 a night in high season. You will want a rental car or a taxi share, since the buses are sparse.

Cruz Bay is the social alternative, about 20 to 25 minutes away. It has the ferry dock, the most restaurants and bars, the safari taxis and the easiest way to meet other travelers. Cheaper rooms and shared houses cluster here, and camping at Cinnamon Bay is the lowest-cost option on the island, from about US$50 a night for a bare site. Stay in Cruz Bay if you want company and easy transport. Choose Coral Bay if you want a quiet base near the east end trails.

🛡️ SafetyScams, Hazards, and Annoyances

Waterlemon Cay beach is a calm, well-regarded snorkeling spot with little to worry about if you pay attention. The bay is sheltered, but the water around the cay itself can have a steady current, so swim out along the shore and enter on the protected side. Waves are small, and conditions turn rougher after winter swells or storms. Stingrays and turtles are common in the seagrass, so shuffle your feet when wading. Sea urchins and fire coral sit along the rocks, so keep your fins off the reef. The sun is strong all year, and shade is limited, so wear reef-safe sunscreen and a rash guard. Few people are around early, but lock valuables out of sight in your car at the trailhead.

Passenger ferries run from Red Hook, St. Thomas, to Cruz Bay in about 20 minutes for roughly US$9 to 10 one way. From the Annaberg parking area it is an easy 15 to 20 minute walk on the Leinster Bay Trail. Taxis from Cruz Bay cost around US$14 to 20 per person for a ride.
Waterlemon Cay beach is mainly a snorkeling spot, and one of the best on St. John. Swim about 100 meters out to the cay to see turtles, rays, starfish and healthy reef in 2 to 6 meters of water. The beach itself is narrow and rocky, so swimming is fine but not the draw, and there is no surfing. Rent gear in Cruz Bay for about US$10 to 15 a day.
Waterlemon Cay beach has no separate entry charge, but it lies within Virgin Islands National Park, which charges no entrance fee; its only beach fee is US$5 per person at Trunk Bay. Parking at Annaberg is free, and the Annaberg Sugar Mill ruins nearby are free to explore. Bring your own water and snacks, since there are no shops or facilities at the trailhead.

We 💚 feedbackSumming up the experience

Waterlemon Cay beach catches people out when they swim straight past the cay’s outer edge, where the current pushes hard. Stay on the sheltered side, circle the island slowly, and turn back if you feel a pull. I would wear a rash guard, since the walk is shadeless and the sun on your back while floating is relentless.
