Here is a small sample size of the time we spent in Rocky Mountain National Park, located near Estes Park, Colorado. The two featured trails are the Alberta Falls trail near Bear Lake (also part of the Bear Lake Corridor), and the Alpine Ridge Trail further into the park. The Alpine Ridge trail involved a stair climb, in which we really noticed the thin air people had mentioned.

Enjoy! Oh, and if you decide to travel here, make sure to pack some lotion and some chapstick!
