St. John snorkeling, from the beach and by boat

From the beach: where to snorkel on St. John

For the best snorkeling on St. John without a boat, the table ranks the eighteen spots reached from the sand by the score each beach page carries, then by the measured time from Cruz Bay. Thirteen score 4, four score 3, and Great Cruz Bay, sand and sea grass in an anchorage, scores 2. Most sit on the North Shore, inside the park and within 25 minutes of town.

Drive and walk times measured on island roads and paths; Waterlemon's walk is the National Park Service's count.

Caneel Bay. The park describes a narrow reef running along the shoreline east from Honeymoon to Caneel, so swim the edges, not the middle of the sand. Boats use a marked channel here.

Hawksnest. Three small fingers of elkhorn coral start at the sand. The park asks you to swim around each reef, never over its shallow top, because elkhorn is federally protected and breaks easily.

Trunk Bay. The marked trail runs about 300 feet along the west side of Trunk Cay, with plaques on the bottom naming what you see. This is the Trunk Bay snorkeling everyone means, and the only spot with a fee.

Solomon Beach and Honeymoon Beach. The walk starts at the park visitor center dock, and Honeymoon is also 7 minutes on foot from Caneel Bay. Off the rocky point that divides the two beaches, the park counts five corals: brain, lettuce leaf, elkhorn, mustard hill and pillar.

Cinnamon Bay. The park puts pillar coral on the cay's northwest corner and a strip of shallow sand on its south side to rest on before the swim back.

Maho Bay. Green sea turtles graze the seagrass, seen most in the early morning and late afternoon, and the coral is at the western side and the northeast rocks.

Francis Bay. The park names it for beginners: calm water from the west end, and the rock shoreline at the north end.

Waterlemon Cay. A drive, a walk and a swim out from the Leinster Bay shore: 27 minutes to the Annaberg lot, then 20 minutes on the trail. The park warns of a strong current on the north side of the cay, facing Tortola, and says to stay on the south side.

Haulover Bay. Two pebble beaches, north and south, from one stop; the park describes boulders and coral out along both sides of each bay.

Hansen Bay. Outside the park. No authority rates it; two local guides send snorkelers to Pelican Rock, out from the left side of the beach.

Salt Pond Bay. The walk from the lot is the half mile the park describes. It points to turtles and southern stingrays near the mooring field.

Lameshur Bay. The park recommends four-wheel drive for the road, and the tip of Yawzi Point is where it sends snorkelers.

The four 3s are fair, and good only at the edges on a calm day. Frank Bay is 9 minutes on foot from the ferry dock, with patch reef toward Gallows Point. Oppenheimer Beach is 9 minutes by car; its shallow reef is recovering from construction runoff, so swim the eastern edge. Denis Bay is a 10 minute drive to the Peace Hill lot and 4 minutes down a path, with rocks at either end. Jumbie Beach is 11 minutes by car, with a reef off the right side toward Trunk Bay. Brown Bay, which the park reaches by trail or boat over seagrass, has no page here and no score.

By boat only: Lovango Cay and the BVI

Two stops on a St. John boat day cannot be reached from shore, and no leg to either is measured here. Who takes you is a charter's job, and this page names no boat.

Lovango Cay. By boat only, off St. John's west end. The island is private, and Lovango Resort & Beach Club says on its own page, as of October 2026, that guests arrive on the resort's private ferry on a scheduled trip or by boat, with moorings for boaters who come for food, drink and the beach club. No authority describes its reef, so it carries no score.

The British Virgin Islands. By boat only, and across a border. Every visitor needs a valid passport book or a US passport card, per the Government of the Virgin Islands in a release of March 20, 2025. The BVI National Parks Trust lists Sandy Cay among its island parks and sells park tickets and a marine permit on its own site, as of October 2026. Check what your boat has arranged before you leave the dock.

When the North Shore is too rough to snorkel

In winter. The National Park Service says cold fronts moving off the continent sometimes bring the Christmas winds down from the north, and that they can put large waves on the North Shore beaches. On those days the park wants swimmers to take great care getting in and to do what the posted signs and its rangers say. The park names no months; it says only that winter tends to bring stronger winds and less rain, and summer more rain and lighter winds.

The tradeoff is that most of the 4s face that shore. On a north swell day the park names Maho Bay and Francis Bay as less affected than the rest of the North Shore, and a north swell still cuts visibility there. Salt Pond Bay and Lameshur Bay are on the south shore, a 41 and 45 minute drive away, and the day is planned around that drive.

The park's rules for snorkelers in the water

Snorkel next to the beach and inside the boat exclusion areas, the stretches marked by white oblong buoys reading NO BOATS. The park's Superintendent's Compendium, updated October 6, 2026, prohibits snorkeling in the boat channels, the shipping lanes and the dock areas.

Stand only in sand, which is how the park puts it at Leinster Bay, where long-spine urchins sit on the rocks at the entry. Swim around a shallow reef rather than over it. The compendium also makes it illegal to damage coral while climbing onto the rocky cays.

The park's snorkeling page says a reef safe label is not regulated, and lists five ingredients to avoid: oxybenzone, octocrylene, octinoxate, butylparaben and 4-methylbenzylidene camphor. Read the label, or wear a rash guard.

Boats of 60 feet or less may not anchor in the park and must use its moorings, per the compendium, and anchoring is prohibited in the Virgin Islands Coral Reef National Monument.

Snorkel gear: bring your own or rent it

You do not need to buy gear for St. John. Three beaches rent it: Trunk Bay, where rentals are among the amenities the $5 fee pays for; Maho Bay, where the park lists snorkel gear across the street from the sand; and Cinnamon Bay, where Cinnamon Bay Resort & Campground charges $10 a day or $50 a week for a mask, fins and snorkel, 9 am to 4 pm, as of October 2026, prices subject to change. The park's record has the campground closed in September and October. No source we read lists rentals at the other spots, and the farthest of them are a long drive past the last rental desk.

Which St. John reef for a first trip, and which next

For a first reef, Trunk Bay or Francis Bay: the park writes up both for beginners, and Trunk Bay has the marked trail, the showers and the rentals. For turtles, Maho Bay at either end of the day. For a second trip, Waterlemon Cay, which more than one local guide puts at the top of the island and which takes the most effort of any spot on the North Shore. On a ship day in Charlotte Amalie, Trunk Bay fills with the day trips from St. Thomas, and the free beaches either side of it are the better use of the morning.
