Following pickup at your hotel in St Lucia, board a coach for the scenic ride to the west coast of St Lucia.
Upon arrival at Fond Gens Libre, named for the freedom fighters who used the area as a hideout during the 18th-century slave rebellion, meet your guide at the nature interpretation center. Peruse the center's exhibits to learn about the wildlife and native flora found in the area, which will be helpful later to identify those species on your hike.
Start up the Gros Piton Nature Trail with your guide, the first section of which is a moderate trek around the base of the mountain. As you wind around the mountain, enjoy panoramic views of the Caribbean Sea and Choiseul Village. Look for local birds, some of them rare, like the St Lucia black finch and the St Lucian oriole. At Anse L'lvrogne Canyon, explore the hideouts, tunnels and caves that were used by freedom fighters centuries ago.
The second part of the climb is strenuous, and suitable only for those in good physical condition. The summit of Grand Piton affords fantastic views of the entire island of St Lucia, as well as the twin peak of Petit Piton in the near distance.
After the 4-hour round-trip hike, return to the coach for transportation back to your hotel.
