Río Vero
verified
Ungraded
Moderate flood risk
Alquezar, Huesca
The signature aquatic walk of the Alquezar side of Guara: limestone narrows, blue water, no rope work, exit at an ancient dam onto the trail back into Alquezar.
Park near the small dam at the listed coordinates and descend the obvious path in about 15 minutes, or start from Lecina to the northwest (25 minutes downhill). Exit canyon right at the old dam and follow the maintained trail up to Alquezar or down to Puente de Fuendebaños. Wetsuit required by park rule even in midsummer; the water is cold.
