There are two ways to access Ptarmigan Trail, one is by Angler Mountain Trail
and the other is starting from the Ptarmigan Trailhead up above the highway. If you start from the Ptarmigan Trailhead it is slightly longer but beautiful nonetheless.

If there is any chance of thunder and lightning do not attempt to summit Ptarmigan. Once you a get a couple miles above treeline there is nowhere to take cover.
It starts with a steep climb crossing a residential road and then through a large meadow. Just before you hit the one mile mark, you'll enter into the trees and descend for about 1/4 of a mile before the powerlines. Cross under the powerlines back into thicker forest and there you'll find the trail begins to ascend again.
After a couple of miles, you'll pass Angler Mountain Trail
on your right intersecting with Ptarmigan Trail. A half mile after this junction is a bench that overlooks the Gore Range on your left. This is a nice turning around point if you want a shorter run. But, if you are ready to summit, continue on up around the next corner. This is where it starts to get steep, but the trail is still nice for running. The switchbacks start at this point, they are gradual, for the most part. Around mile 4.5 you'll arrive at treeline. Continue straight up the trail, and you'll reach an intersection with Ptarmigan Pass Trail and Ptarmigan Peak
Trail. Continue straight on Ptarmigan Peak
Trail. Another mile and you'll reach the summit! Now for the fun part, turn around and run back down to the car, making sure to stay left at the Angler Mountain Trail
