Mosquito Peak requires a short bit of off-trail rock hopping in order to reach the 13,781 foot summit. You'll likely have the peak all to yourself as not many people try to bag this 13er. The views from the summit are great, and you can even see some of the Front Range Peaks on a clear day. This summit is often done in unison with some of the other trailless 12,000 and 13,000 foot peaks in the area. It's more of a hike on the way up, but you can mainly run the old mining roads back down.
