Orosi is a town in the Cartago Province in Costa Rica, about 30 kilometers south of the capital San José. Orosi is situated on the Reventazón River in the Orosi Valley. The cultivation of coffee is the leading industry in the area. Orosi has a population of approximately 4,600 and has the oldest Catholic church still in use in Costa Rica. The church, Iglesia San Jose de Orosi, was built in 1743 and has been unaffected by Costa Rica's frequent earthquakes.
A few kilometers away, at the southern end of the valley, the road ends and the Parque Nacional Tapantí Macizo Cerro de la Muerte begins. This park covers about 600 km² and forms the northernmost section of a massive collection of nature parks that extends into Panamá (the largest of which is the Parque Internacional La Amistad). As a result, wildlife abounds. However, access is difficult and largely restricted apart from a few kilometers of easy trails. The abundance of birds makes it a popular place for ornithology studies. Part of the reason for the abundant growth is the heavy rainfall, which ranges up to 7000 mm in the mountains.
