Maho Bay, St. John: A Captain's Guide to the USVI's Best Turtle Anchorage

If a guest asks me to pick a single beach to land their first morning on the north shore of St. John, the answer is almost always Maho. It's the easiest landing, the calmest water, the most reliable turtle swim in the USVI, and the bay that bends the least to wind and swell. Trunk is the famous one; Maho is the one you actually enjoy.

What makes Maho different

Three things. The bottom — sand and seagrass instead of coral, which means flat water on entry and the calmest swimming on the north shore. The turtles — green sea turtles graze the seagrass meadows here in numbers you won't see anywhere else in the USVI. And the access — the beach drops straight to the water with no rocks, no sharp coral, and a slope so gentle you can walk halfway to the boats.

The turtles

Green sea turtles live in Maho year-round. They surface to breathe every five to seven minutes, then drop back to the seagrass to graze. On a normal morning swim you'll see two to five. Rules: stay at least six feet back (it's federal law in the park), don't chase them, don't touch, and don't get between a turtle and the surface — they need to breathe. Float quietly above and they'll often surface a few feet from you on their own.

Anchoring (or rather, mooring)

Maho is inside Virgin Islands National Park. Anchoring on the seagrass is prohibited — the chain scars the grass that the turtles depend on. Park-maintained mooring balls are first-come, first-served and clearly marked. We pick one up, the boat sits flat, and we're swimming inside ten minutes.

When Maho is at its best

Early morning, before the day-trip catamarans arrive (most show up between 10 and 11). On a day with strong easterly trades, when Trunk and Cinnamon are getting wind-chop and Maho stays glassy. As the first stop of a north-shore day, so the turtle swim is the wake-up and Francis or Leinster is the afternoon.

Snorkeling beyond the turtles

The middle of the bay is sand and seagrass — the turtle zone. The rocky points on either end have small reef sections worth a look: more parrotfish, the occasional ray, schools of grunts in the shadows. The serious reef snorkel on this side of the island is Waterlemon Cay in Leinster Bay, one cove east — we'll usually pair the two.

Ashore

A small snack stand, restrooms, and one of the easier walks in the park. The beach is long and flat. The road runs close, so you can walk a half-mile in either direction along the shore. There's no marina, no rental shacks, no busy infrastructure — which is the point.

Overnight at Maho vs. Francis

Maho is fine for a night in settled conditions, but on bigger trade days it picks up swell wrap-around the eastern point and the boat rolls more than guests want for sleep. Francis Bay, the next cove east, is meaningfully calmer overnight and has the better sunset angle. We often spend the swim at Maho and move 15 minutes east for the evening.

How it fits into a charter week

Maho is the right answer for the first or second morning of a north-shore day. Pair it with Trunk early (if you want the photo) and Leinster or Francis for the afternoon. On a strong-trade day, it's often the only north-shore anchorage that stays comfortable — making it the de facto base for the day. Tell us turtles matter and Maho is on the itinerary.
