Francis Bay, St. John: Snorkeling, Beach & Boardwalk Guide

I almost skipped Francis Bay entirely. I had already spent three days working my way through the beaches of Virgin Islands National Park, and my sunburn was reaching a shade of red my dermatologist would not approve of. But a ranger at the visitor center in Cruz Bay told me Francis Bay was where he went on his days off. That was enough to change my plans.

He was right. Francis Bay turned out to be one of the best beaches I visited on St. John, and I have kicked myself for nearly leaving it off the list. It does not have the name recognition of Trunk Bay or the sea turtle crowds of Maho Bay, but what it lacks in fame it makes up for in quiet, clear water, and some of the better snorkeling on the island.

Where Francis Bay Sits, and How to Reach It

Francis Bay sits on the north shore of St. John, just west of Maho Bay. The two bays share a coastline separated by a rocky point, and you can walk between them along the shore when the tide cooperates. Francis Bay is about a 20-minute drive from Cruz Bay, where the ferry from St. Thomas drops you off.

Getting to St. John itself is the first step. Fly into Cyril E. King Airport (STT) on St. Thomas, then take the car ferry or passenger ferry across to St. John. Most visitors use the Red Hook to Cruz Bay passenger ferry, which runs roughly every hour and costs $13 per adult each way as of 2026. The crossing takes about 20 minutes. From Cruz Bay you will want a rental vehicle, since the north shore beaches are spread out and public transit is limited.

117 public lands destinations are under threat. Get the free briefing that 27,000+ people use to stay informed and take action.

There are two ways to reach the beach once you are on the north shore. You can park at Maho Bay and walk west along the shoreline, which is the scenic route and gives you a nice sense of discovery when Francis Bay opens up in front of you. Or you can drive past Maho Bay, continue toward the Annaberg Ruins, and use the dedicated Francis Bay parking lot. From the lot, the beach is a short walk down a path.

I recommend sandals for the walk from the parking lot. The ground between the lot and the sand is rocky and uneven, and I watched two folks in flip-flops have a rough time of it. Something with a strap, like a basic sport sandal, will save you some trouble.

What Makes Francis Bay Worth the Drive

Francis Bay is a crescent of white sand backed by sea grape trees and coconut palms, with the green hillsides of St. John rising behind it. The water is that ridiculous shade of Caribbean turquoise that looks faked in pictures but is even more vivid in person. I shot about 200 frames here, and every one needed the saturation pulled back in post because the raw files looked unrealistically blue.

The bay is tucked behind a protective point, which keeps the water calm most of the time, with gentle swells that barely qualify as waves. That makes Francis Bay good for swimming with kids, floating on your back, or wading in up to your waist and staring at the horizon while your brain goes quiet.

The crowd situation is the real selling point. On the day I visited, a Saturday in February, there were maybe 15 people on the entire beach. Trunk Bay, by comparison, had what looked like 200. Maho Bay was somewhere in between. Francis Bay tends to draw folks who already know the island, and that self-selecting crowd keeps things mellow.

Snorkeling at Francis Bay

The snorkeling at Francis Bay is very good and, in some ways, better than the more famous spots on the island. While Trunk Bay has its underwater trail, which is genuinely worth doing, Francis Bay has a rockier bottom with more coral structure, which means more fish and more interesting things to look at below the surface.

I spotted green sea turtles within 10 minutes of getting in the water. They were grazing on seagrass in the shallows, completely unbothered by my presence. I also saw rays gliding along the bottom, schools of blue tang, and a handful of parrotfish working over the coral. Visibility was roughly 40 to 50 feet, which is about as good as Caribbean snorkeling gets.

A few notes on the turtles. Green sea turtles are protected under the Endangered Species Act, and it is a federal crime to touch one. I know the temptation is real when one swims within arm’s reach, but keep your hands to yourself and give them room. The turtles at Francis Bay are used to snorkelers and will not flee if you stay calm and keep your distance.

Bring your own snorkel gear if you can. A basic mask and snorkel set works fine. If you do not have gear, rental shops in Cruz Bay will set you up for the day.

The Francis Bay Boardwalk and Bird Pond

One thing that sets Francis Bay apart is the boardwalk trail that leads through a small salt pond and mangrove wetland at the eastern end of the bay. The boardwalk is short, maybe a quarter mile, but it passes through habitat that supports herons, pelicans, and several species of shorebirds.

I watched brown pelicans diving for fish just offshore during my visit, which is always entertaining. The birds fold their wings and drop like missiles into the water, then bob back up with, sometimes, a mouthful of fish. I could have watched them for an hour.

The path also connects toward the Annaberg Ruins, the remains of a Danish sugar plantation built and worked by enslaved Africans in the 1700s and 1800s. It is a sobering and important site that gives context for the colonial history of these islands. If you are already at Francis Bay, the short walk to Annaberg is well worth the detour.

Best Time to Visit Francis Bay

For swimming and snorkeling, midday is ideal. The sun is high enough to light up the bottom clearly, which makes spotting turtles and fish much easier. The trade winds tend to pick up in the afternoon, so getting your snorkeling done before 2 PM gives you the calmest water.

Because Francis Bay opens to the west and northwest, it leans toward a good late-day light rather than sunrise. If you can swing it, the hour before sunset turns the whole crescent gold and the crowd thins to almost nobody.

Photographing Francis Bay

The best vantage point for photographing Francis Bay is not from the beach itself. It is from the America Hill Ruins, a short but steep hike to the remains of an old estate house on the hillside above the bay. From up there you get a wide view of the entire crescent of white sand, the turquoise water, and the green hills framing it all. On a clear day you can see across to the British Virgin Islands.

Know Before You Go

  • Getting there: Ferry from St. Thomas (Red Hook to Cruz Bay, about $13 per adult each way in 2026), then roughly a 20-minute drive on the north shore. Rental car strongly recommended.
  • Parking: Dedicated Francis Bay lot near Annaberg, or park at Maho and walk west along the shore.
  • Fees: There is no general entrance fee for the park. Unlike Trunk Bay, Francis Bay has no amenity fee.
  • Facilities: Limited. There are restrooms near the lot, but no snack bar or gear rental. Pack water, sun protection, and your own snorkel gear.
  • Water conditions: Usually calm and protected, good for families and beginner snorkelers. Trade winds pick up in the afternoon.
  • Wildlife: Green sea turtles are common in the seagrass. Keep your distance and never touch them.
  • Time needed: Plan on a half day if you want to snorkel, walk the boardwalk, and detour to Annaberg.
