Mt. Chapin, Mt Chiquita, Ypsilon Mountain (The CCY)

The hike begins from the Chapin Creek Trailhead, located on Old Fall River Road. Near the trailhead there's enough room for roughly 12 to 15 vehicles in a series of pull-offs starting at the trailhead. With limited parking you'll definitely want to arrive here first thing in the morning. 

From the trailhead the hike begins with a fairly steep climb before reaching a split in the trail. At just over one-tenth of a mile you'll see a sign indicating that you should turn right to continue towards the Chapin, Chiquita and Ypsilon summits. Although there's very little exposure to any steep drop-offs, this route is still a challenge due to the rugged terrain it traverses over. In her Complete Hiking Guide, Lisa Foster rates this hike as a Grade II, Class 2 route – due to travel over talus slopes and long exposure to thunderstorms.

At about a 1/2 mile the trail emerges from the treeline, while Chapin, Chiquita and Ypsilon come into view for the first time. At two-thirds of a mile you'll reach another split in the trail. The sign at the junction states that you should turn right to continue towards "all summits". 

Beyond the junction the recommended trail begins to climb the western slopes of Mt. Chapin, and eventually begins to skirt around the northwestern slopes as it proceeds towards the Chapin-Chiquita saddle. As the trail continues you'll traverse through a couple of long talus fields. Although a little rugged, it's not exceedingly difficult. we will following the contour of the mountain as it makes its way towards the saddle.

At 1.7 miles, just before reaching the saddle, hikers will pass an unmarked side trail leading to the summit of Mt. Chapin. From this junction you're roughly one-third of a mile and almost 400 feet below the summit of Mt. Chapin. Continue on towards Chiquita summit staying to the left and proceeding towards the summit with outstanding views of Longs Peak.

After summiting Mt Chapin, re-trace the trail back to the Chapin-Chiquita saddle and then climb 1,000 vertical feet to Mt Chiquita's summit. We will then descend about 300 vertical feet to the saddle between Chiquita and Ypsilon and hike 700 vertical feet up the steep slope to the summit of Ypsilon Mountain. Great views of Desolation Peak, the rest of the Mummy Range, including Lawn Lake Valley.
