About This Route
Rio Chimehuin near Junin de los Andes in northern Patagonia, Argentina, is a dry fly paradise for large brown trout. Key sections include the upper reaches from Chapelco Lake outflow and the famous Vado de las Águilas crossing. Accessible via RP23 from town, fish from shore or drift boats October to April. This freestone river in Lanin National Park requires permits; follow NPS-style protocols for minimal impact.
Safety Considerations
Fast pocket water and boulders pose slipping risks; use quality traction soles. Extreme temperature swings from 90°F days to freezing nights heighten dehydration and frostbite dangers. Heavy rains cause flash floods; check USGS-equivalent gauges via local fly shops. No studded boots per lodge rules to protect equipment. Black flies and mosquitos peak at dusk; apply DEET. Remote; inform someone of your itinerary.
