Brown Bay Trail

Overview

Brown Bay Trail is a moderately challenging 1.6-mile out-and-back to a quiet north-shore bay on St. John. Plan on about 60–90 minutes total. It’s a classic Coral Bay–side hike: up and over a dry, rocky hill with big views, then down to a tucked-away beach where, on the right day, you can snorkel with very few people around.

The Hike

From Route 10 on the Coral Bay side, the trail climbs steadily on loose rock to a low crest with sweeping looks over Hurricane Hole and toward the British Virgin Islands. Shade is limited and the tread is rocky with some thorny brush and cacti—sturdy footwear beats flip-flops every time. After the crest, descend toward Brown Bay through dry coastal vegetation. Expect a less-traveled feel; you may see goats on the hillsides.

Brown Bay Beach and Snorkeling

The beach is a narrow strip that can be sandy with seagrass in the shallows. When conditions line up, the water is calm and clear with reports of sea turtles, octopus, schooling fish, stingrays, and conch, especially along the bay’s sides. Brown Bay is a turtle-nesting area—give posted zones and dunes space. Do know the bay can collect sargassum in late spring and summer; when it’s in, the smell and nearshore muck can make snorkeling a no-go. Check conditions with the Cruz Bay Visitor Center or ask locals in Coral Bay before committing your beach day here.

Extensions and Alternatives

If you’re up for more, continue on connected paths toward the Murphy Great House ruins for breezy views, or push on to Waterlemon Bay/Cay for some of the island’s standout snorkeling. These add distance and elevation beyond the 1.6-mile out-and-back.

Best Time to Hike

December through June generally brings the most pleasant hiking and water conditions. Start early—by 8–9 a.m.—for cooler temps and softer light. Afternoons get hot, and the climb back to the road feels spicier in the sun. If sargassum is in the bay, pivot your snorkel plans to nearby Waterlemon instead.

Practical Tips

Bring real traction shoes, a hat, reef-safe sunscreen, bug spray, and at least 1–2 liters of water per person. Pack swim gear and optional water shoes for the rocky entries. Dogs are allowed on leash. Expect limited parking and light crowds—often you’ll have long stretches to yourself. Not the best pick for very small children due to heat, rocks, and thorny sections.
