I climbed Bottle and Ptarmigan Peaks from Keyser Creek. We climbed the peaks from the west. The trail was faded, but we made our way to Bottle Pass and then climbed Ptarmigan Peak. After eating lunch at the summit, we returned to Bottle Pass and climbed Bottle Peak before heading back down to the vehicle. It was sunny the whole time and there were no mosquitoes. It was a perfect day.
I climbed Bottle and Ptarmigan from the Fraser Experimental Forest. At the time the road was open all the way to the beginning of the trail (it's closed now).
