Hike around the ruins of Morne Fortune (“good luck hill”), a former military outpost overlooking the harbor it was meant to protect. The site was hardly good luck during the 18th century: Several bloody battles between the French and the British took place here. The remaining structures on Morne include guard cells and a powder magazine, the building used to store gunpowder and ammunition, as well as French and British burial grounds. At the top of the hill, near a memorial to the British infantry regiment that captured Morne Fortune in 1796, you’ll find a great spot for a panoramic view over Castries and its harbor.
