Saint Kitts: Brimstone Hill Fortress and Basseterre
Saint Kitts grew sugar for three hundred years, and Brimstone Hill Fortress is what that wealth was worth defending. The UNESCO-listed fort sits 220 metres up, its cannon still aimed out over the Caribbean Sea, and it is the best place to understand the shape of this narrow volcanic island. Basseterre, the capital, takes an afternoon on foot: the Circus roundabout, the Georgian buildings along the waterfront, and the National Museum. Dinner is down by the harbour, with Nevis Peak across the water.
