Posada Natura is operated by Eco Era, a U.S.-based non-profit (501c3) established in 1991 to protect & steward 10,000 acres of primary rainforest in the Cerro Nara watershed of Costa Rica. This area houses the Rio Naranjo and Rio Savegre watersheds, and constitutes some of the cleanest water in Central America. It is one of the most biodiverse areas on earth with several endemic species and is part of the stretch of unbroken rainforest that reaches from the Pacific Ocean to the Caribbean Sea.

Every stay at Posada Natura directly benefits this rainforest and watershed.
