Hiking and Running
Hikers are spoiled for choice in the area around the ranch. There are so many trails that there are several books about them. (One local rite of passage is the hike from Crested Butte to Aspen.) You can always just take off on your own, as well. The ranch is full of beautiful places to explore.
Runners will find a wealth of quiet roads and trails, for both the beginning runner and the determined distance athlete.
