Gruta de Huagapo
Head northwest of Tarma 28 km (17 miles) to Palcamayo, then continue 4 km (2½ miles) west to explore the Gruta de Huagapo limestone cave system, a National Speleological Area. Guides live in the village near the entrance and can give you a basic short tour, but you'll need full spelunking equipment for deep cavern explorations. Numerous tour operators in Tarma offer day-trips to the caves and the surrounding villages. It is also possible to arrive at the caves independently by taking a colectivo at the corner of Jr. 2 de Mayo and Jr. Puno.
