Río Claro Natural Reserve is a pristine protected area in Chile renowned for its crystal-clear river, lush temperate rainforest, and striking marble canyon landscapes, offering diverse outdoor activities amid rich biodiversity.
Río Claro Natural Reserve is located in the Maule Region of central Chile, encompassing approximately 600 hectares around the Río Claro river. The reserve is famous for its striking marble canyon formations carved by the river's turquoise waters, set within a temperate rainforest endemic to the southern Andes. The area is part of the Valdivian temperate forest biome, characterized by abundant native species such as coigüe (Nothofagus dombeyi), arrayán (Luma apiculata), and ancient lenga trees. Wildlife in the reserve includes endangered species like the pudú (world’s smallest deer), various species of birds, and several small mammals. The reserve’s geology, featuring unique marble sculpted by river erosion, creates natural pools and waterfalls that attract nature lovers and photographers. Visitors have access to well-marked trails ranging from easy walks to moderate hikes, allowing exploration of the canyon, native forests, and viewpoints overlooking the river. Outdoor recreation opportunities include hiking, swimming in natural pools, birdwatching, and picnicking. The reserve is managed with a focus on conservation and sustainable tourism. It provides a refuge from urban life and a chance to experience Chile’s native forest ecosystems in a relatively unspoiled setting. The nearby town of San Clemente serves as the typical gateway, offering accommodations and local cultural experiences. Río Claro’s blend of natural beauty, geologic intrigue, and recreational access continually draws eco-tourists seeking both adventure and tranquility.
