Descending to the Sea: Hiking Reef Bay Trail on St. John
A steep rainforest walk to sugar-mill ruins, petroglyphs and a snorkeling reef—perfect for half-day explorers.
The first steps put the world into a different scale. The gravel gives way to red clay, then to a narrow footpath punched through kinked blackberry and cedar saplings. Above you, the rainforest holds its breath; below, the Caribbean is a smudge of impossible blue, its reef line a pale reef-bone running parallel to the shore. By the time the trail pitches down to the bay you can feel the ocean’s invitation: a tang of salt, a breeze that pushes through the trees like an usher.
Trail Wisdom
Start at dawn
Begin early to avoid heat, secure parking in Cruz Bay, and enjoy quieter trails and better snorkel visibility.
Pack plenty of water
Bring at least 2 liters per person — there’s no reliable potable water on the trail.
Wear grippy shoes
Choose trail shoes or hiking boots with good tread for muddy or rooty sections on the descent and climb back.
Use reef-safe sunscreen
Protect corals by using UV protection labeled reef-safe when snorkeling off the bay.
