This two-day Patagonia hike leads to Refugio Otto Meiling on the slopes of Cerro Tronador, one of the most prominent peaks in the Bariloche region. The route climbs through coihue and lenga forests before emerging onto a high rocky ridge that culminates at the refuge (1,905m). Positioned between the Castaño Overa and Alerce glaciers, the stay offers a unique opportunity to witness active glacial calving. The trail follows a well-defined path of forest floor and alpine rock, with a final sustained push to reach the rocky spine where the hut perches.

Mission Directive / X-Factor

“The most distinctive element of this route is the proximity to active glacier fronts. From the refuge, the sound of shifting ice from the Castaño Overa glacier is frequently audible, particularly during warmer conditions.”

Hazard Assessment

crevassesPRIORITY 1

Venturing onto the glaciers without a guide or technical training is extremely hazardous due to hidden crevasses.

MITIGATION: Do not walk on the glacial ice past the refugio without a certified mountain guide. Stick to the marked rocky trails.

rapid_weather_changesPRIORITY 1

High alpine exposure means severe storms can blow in quickly from the Pacific, even in summer.

MITIGATION: Check latest forecasts with Club Andino Bariloche (CAB). Carry high-quality wind and rain protection.
