Río Claro is an Andean river located in the Maule Region of Chile, rising in the high Andes at the confluence of the Los Cajones River and Del Planchón River before flowing down to empty into the Teno River near the city of Los Queñes. Fed by Andean snowmelt and glacial sources, this freestone river carries the character of a classic mountain stream — cold, clear, and dynamic — making it a compelling destination for trout anglers willing to explore Chile's interior river systems. The river's Andean origins give it the kind of clean, well-oxygenated water that supports healthy trout populations, and its remote mountain setting adds a sense of adventure to any fishing trip.
