Backcountry ski touring out of Boulder comes in two flavors: Indian Peaks and Front Range. The Indian Peaks, located about an hour's drive from Boulder, are less developed but have some fantastic areas: Heart Lake, Arapahoe Lakes, Mount Audubon, and St. Mary's Glacier are all relatively close to Boulder. However, if you want more immediate access to backcountry fun, try Berthoud Pass or Loveland Pass. Both begin off the top of paved, maintained passes and taking laps is common -- if you don't have a vehicle to serve as a shuttle, try sticking your thumb out. Locals are good for giving lifts back up the passes! Spring is the best time to tour, when avalanche danger is less and the snow is more consolidated.
