Fall in Colorado is absolutely beautiful... the peaks get a dusting of snow, cooler temperatures make everything more comfortable, and the leaves are changing up high. Sarah and I hiked the Ptarmigan Trail in Silverthorne on Saturday, and it didn't disappoint. The pictures truly don't do justice to how beautiful this trail is. Views for miles and 13,000 foot peaks everywhere. Here are a few from the five and a half mile hike.
