St. Lucia is divided into eastern and western halves by Barre de l'Isle ridge. A mile-long (1½-km-long) trail cuts through the reserve, and four lookout points provide panoramic views. Visible in the distance are Mt. Gimie, immense green valleys, both the Caribbean Sea and the Atlantic Ocean, and coastal communities. The trailhead is about a half-hour drive from Castries. It takes about an hour to walk the trail—an easy hike—and another hour to climb Mt. LaCombe Ridge. Permission from the St. Lucia Forestry Department is required to access the trail in Barre de l'Isle; a naturalist or forest officer guide ($10) will accompany you.
