Centro Biológico Santuario De Mariposas Aguas Silvestres
Lonely Planet review
You’ll need your own wheels, or you can make arrangements through Rancho Leona (below), to visit this butterfly sanctuary in the mountains, run by the energetic Edgar Corrales. Guided hikes (in Spanish) take you through the rainforest along a waterfall trail and include a tour of the butterfly garden. You can also stay overnight in the rustic bunkhouse; the rate includes dinner, breakfast, a half-day tour of the local rainforest with a swim in the lagoon, and lunch on your return. However long your stay, be sure to bring bug repellent, as butterflies are not the only insects living up there.
To get here on your own, turn onto the Pozo Azul road and follow the brown wood signs to the sanctuary, which is about 10km up the mountain, near the village of San Ramón.
