Dragontail Peak (8840') is "A lengthy and difficult hike up an iconic peak inside the Enchantments.  Climbing gear and expertise required."  The route begins at the Colchuck/Stuart Lk TH, follows the trail trail to Colchuck Lake and around the south end of the lake. Climbers ascend Aasgard Pass and ascend the snowfield on the eastern slope of Dragontail to the saddle dividing the Enchantments basin to Ingalls Creek.  Then ascend the ridge to the summit. It is around 13 miles TH-to-TH, with 5800+ feet of elevation gain.

Eric Lee established this 100+ km route:

A full circumnavigation of the Yosemite Valley rim on foot. Starting from Bridal Veil parking lot the route climbs to the valley rim trails, follows the trail system over Clouds Rest all the way to Tenaya Lake, before returning along the North rim over El Capitan and down the Old Big Oak Flat Rd back to the valley floor and the starting point.
