America's Wildest Hotels
Dream vacations often call to mind sandy beaches, frosty cocktails and poolside massage service, but adventurous travelers can opt to wrangle cattle, sleep in trees, run zip-line courses and ski trails accessible only by helicopter.
An hour outside of Denver, this 5,000-acre ranch offers snowmobile trails in winter and private access to parts of the Colorado River for fly-fishing and white-water rafting in summer. In lieu of electric heating and cooling, the 16 cabins use geothermal energy and feature fireplaces that burn wood from the ranch. From $143; devilsthumbranch.com.
