About This Route

Less regulated than Torres; self-sufficient required. Wild camping; follow Leave No Trace strictly.
Safety Considerations
Technical passes like La Virgen demand ice axe proficiency; crevasses hidden. River crossings deadly in melt; wade upstream. Multi-day exposure amplifies weather risks; 72-hour food carry. Pumas territorial; hike in groups. GPS tracks from Wikiloc vital; no cell service.
