This challenging hike is a chance to bag 3 summits in Rocky Mountain National Park in a single day. Two of the 3 are over 13,000 feet. Climbing the trifecta of 12,454-foot Mt. Chapin, 13,069-foot Mt. Chiquita and 13,514-foot Ypsilon Mountain is one of the classic hikes in Rocky Mountain National Park. The amazing panoramic views from the three peaks along the "CCY Route" are some of the best in the park.
