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.
Continue ReadingThe 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.
