Trip report
Sep 4, 2016 — Starting from the Half Moon Trailhead, accessible by any car, the Half Moon Trail leads up through pretty forest for a while before reaching Half Moon Pass. From here the trail descends roughly 1000 vertical feet and while it's great for the view of Mount of the Holy Cross, coming back this way required regaining the lost elevation back to Half Moon Pass. The trail crosses over East Cross creek and then continues up easy Class 2 talus using the north ridge of Mount of the Holy Cross, before some minor scrambling to gain the summit. We probably should have turned around because we started to get hailed on, but the rainbow that followed that we saw from the summit was incredible.
A few years later I repeated Mount of the Holy Cross via Halo Ridge, a more adventurous and longer route compared to this standard one that might be worth checking out.
