Head northwest of Tarma 28 km (17 miles) to Palcamayo, then continue 4 km (2½ miles) west to explore the Gruta de Guagapo 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 trips. Numerous tour operators in Tarma offer day trips of the caves and the surrounding villages. It is also possible to arrive at the caves independently
by taking a collectivo at the corner of Jr. 2 de Mayo and Jr. Puno.
