PataLares is the name given by Hans to the rides encompassing the high pamero/puna in the Patacancha highlands then descending valleys via the N side of Pumawank’a from the Chalhua Cocha pass. Via this route we got amazing views of Sahuaisiray and Sirijuani then took parts of the Wakawasi trail to the village of Lares ducking out on partway on the road as a member of the party was feeling altitude sickness. The Patacancha trail starts at 4100m at the pass and has some pedally and climbing bits. It is not a particularly good way to acclimatize because exit to lower altitudes will take a bit of time so be forewarned.
