1. Gros Piton, St. Lucia
Probably the most photographed mountain in the Caribbean (picture a child's drawing of a volcano), the cone of St. Lucia's Gros Piton is also one of its most challenging ascents. It can take fit climbers five to six hours of round-trip walking and scrambling to conquer the 2,600-foot summit, but the views that you'll enjoy less than an hour in — and the sense of accomplishment you'll feel at the top — are worth it.
