Descent

Descent is an out-and-back trail, 1.7 miles each way (3.4 miles round trip) in Oruro, Bolivia, inside Parque Nacional Sajama. It runs between about 16,480 ft and 20,520 ft above sea level, with roughly 4,100 ft of climbing one way. It is alpine hiking on rough, exposed ground where you may need your hands for balance; it is for experienced hikers. Most of the way is dirt. The nearest town is Sajama, about 9.4 miles west of the trailhead. Peaks within about 3 miles include Huancalla Kkollu, Volcán Pomerape and Volcán Parinacota. For camping, Campamento alto and Campamento base are within about 6 miles. Distances, elevations and the route shape here come from OpenStreetMap and the Copernicus 90 m elevation model. Trails, access rules and conditions change, so check locally before you go.
