About This Route
Lake Todos los Santos, known as Emerald Lake for its turquoise hue from glacial silt, challenges advanced stand-up paddleboarders on the 12-kilometer traverse from Petrohué Falls launch to Peulla village. Volcanic Osorno overlooks steaming geothermal vents and monkey puzzle forests, creating a surreal Jurassic-like paddle. Strong thermal winds and microbursts test endurance; ideal for those with surf SUP experience. Local guides from Hotel Peulla emphasize APN permits and weather windows. Spot Andean foxes and rare Darwin's rheas; respect sacred Mapuche sites by paddling wide berths. This route aligns with Leave No Trace water ethics, prohibiting soaps near shores.
Safety Considerations
Frigid 7-11°C (45-52°F) water demands drysuits; geothermal upwellings create unpredictable boils pulling boards under. Winds exceed 60 km/h post-noon, forming breaking waves; launch pre-9 AM. Rapids-like outflows at Petrohué require portage scouting. Isolation amplifies risks; no cell service, carry EPIRB. Follow REI big water protocols: always two paddlers minimum, tethered gear. Volcanic gas plumes from Puyehue can reduce visibility; check GeoRisk alerts. Muscle cramps from 4-hour efforts common; hydrate with electrolytes.
