A couple of winters ago, I did an ascent of Pikes by going up from the Crags, enjoyed some chilli in the summit house, and descended Barr Trail to the A-frame to camp overnight. The next morning I descended to Barr Camp, where I scored some spare pancakes that the boy scout group that was up there didn't eat, then it was out to the Barr TH by noon. I've summitted Pikes 7 times now, with numerous trips on both the Barr and the Crags area, and this trip still remains one of my favorite ever. The summit was still a bit crowded with the train people, but I had the rest of the mountain to myself. The city lights of C.Spgs and sunrise the next day from the A-Frame were very memorable. The only downside is needing to shuttle.
