Cabrits National Park: Fort Shirley and the Wild Peninsula of Dominica
Walk the ramparts, dive the reef—the compact slice of Dominica where history meets the sea.
Continue ReadingThe air tastes of salt and wood smoke as you crest the last ridge above Portsmouth harbor. Below, the town folds into a horseshoe of blue, fishing boats bobbing like punctuation against the open sea. Ahead, Fort Shirley perches on the Cabrits peninsula—stone walls softened by lichen, a watchful ruin that has seen empire and hurricane alike. Walk the trail and the island’s story reads underfoot: fractured volcanic rock, coastal forest that clings to thin soil, and a reef beyond the headland that, depending on season and tide, dares you to dive in.
