Fodor's Expert Review Children's Eternal Rain Forest

The 54,000-acre rain forest dwarfs the Monteverde and Santa Elena reserves. It began life as a school project in Sweden among children interested in saving a piece of the rain forest, and blossomed into a fund-raising effort among students from 44 countries. The reserve's Bajo del Tigre trail makes for a gentle self-guided 3½-km (2-mile) hike through secondary forest. Along the trail are 27 stations at which to stop and learn about the reserve, many with lessons geared toward kids. A separate guided twilight walk with a knowledgable guide ($25) begins at 5:30 pm and lasts two hours, affording the chance to see the nocturnal side of the cloud forest; reservations are required. Much of the rest of the reserve is not open to the public, but the Monteverde Conservation League offers stays at San Gerardo and Poco Sol, two remote field stations within the forest. The $79 packages include dormitory accommodation and meals.
