The standard Colca mountain-bike route begins at Patapampa, at 4,950 meters, and drops into the Colca Valley at Chivay at 3,650 meters. Bikers follow dirt roads along the north side of the river and cross the bridge to Yanque.
Another good option is Naturaleza Activa (Santa Catalina 211, tel. 054/959-822-436 or 958-681-486, naturactiva [at] yahoo [dot] com), which also offers more mellow biking trips around Arequipa’s countryside.
