Atlas › Sierra de Guara - Mascun
Mascún Superior
verified
Ungraded
High flood risk
Rodellar, Huesca
The Guara emblem: a long day with a long approach, 11 rappels up to 115 ft, swift water, and limestone walls that make a strong case for being the best canyon in the range.
Plan the full day. Approach the put-in via the long uphill from Rodellar, descend the slot, exit back through the lower Mascun. Skill threshold is real: this is not a beginner trip. Cold water year round, full wetsuit mandatory.
