About 150 km southeast of San Jose, San Isidro de Perez Zeledn (known locally as Perez) is a starting point for trips into southern Costa Rica - particularly due to its proximity to the unreal splendor of Parque Nacional Chirripo, whose main entrance is located in nearby San Gerardo de Rivas.
The official language is Spanish, but you can find help in English at the Chamber of Tourism. Not many people speak English, but you'll find someone eventually if you keep looking - the locals (Ticos) are very friendly.
The MUSOC bus departs from the Mercado Central and Gafeso. Taxis are in the front of the park.
Tourists usually stay in Hotel Chirrip because it's located in front of the park, and it's easy to get there. The Hotel Nuevo Iguazu is nice too.
