Cloudbridge is a private nature reserve in Costa Rica adjoining the primary forest of Chirripo National Park, a UNESCO World Heritage Site. Volunteers are needed in various areas from conservation work to biomonitoring to construction.

The Cloudbridge Reserve has three purposes:

- To preserve a precious part of the tropical world forever.
- To help reforest those areas which had been converted to cattle pasture.
- To protect the biodiversity for which the neotropical forests, and those in Costa Rica in particular, are so famous.

Volunteers are welcome to come and work on research projects in the reserve (with approval). Cloudbridge has two types of volunteer opportunities, one is geared to people with a biology background who propose a field research project, and the other are general volunteers who work on whatever is needed. Read through the organization’s very thorough FAQ page for the specifics.

The usual stay is 6-12 weeks or more; some have stayed for much longer. A few dedicated volunteers have returned for two or more stints, some have never left.


Volunteers pay a “good faith” fee of $200, of which you get $50 back when you complete your assigned stay and project report. (The remainder goes to reforestation, research expenses, and accommodation upkeep.) The cost of living is low: actual costs depend on the accommodation available. Volunteers live in one of our houses. Transportation by bus to San Gerardo from San Jose runs under $20. Sometimes volunteers make a specific contribution where there’s an identifiable need.
