About Cape Coast

Cape Coast faces the Atlantic in southern Ghana, its whitewashed castle on the shore one of the country's UNESCO-listed trading forts and now a museum and memorial to the transatlantic slave trade. The narrow streets and busy fishing harbour are worth a slow walk, and the canopy walkway in Kakum National Park is a short drive inland. Elmina, with its own castle, is close by. November to March is the most comfortable stretch; the heaviest rains fall around May and June.
