Area Natural Protegida Río Sapo

Lonely Planet review

Southeast of Perquín, the Río Guaco and Río Talchiga tumble over several picturesque waterfalls before meeting southeast of Perquín to form the Río Sapo, considered the cleanest river in El Salvador. An agreement between landowners and the local environmental organization has set aside 6000 hectares (about 14,826 acres) to create the Area Natural Protegida Río Sapo .
