Going to Extremes - Red Mountain Spa

Despite a recent shift away from high-burn workouts at most American spas, some still make it their first priority to keep the body beautiful - and fit.  Red Mountain's stunning wilderness setting, next to Snow Canyon State Park, allows for aggressive workouts during guided hikes and mountain biking trips.  The SpaSports program includes rock climbing ($100) and kayaking ($75) near Zion National Park.  Guests can ride horseback on trails in Pine Valley ($70), or trek the Grand Canyon rim to rim on a backcountry wilderness campout ($600).

The spa tailors weeklong stays to each guest's physical ability and stamina.  It has hiking (four levels of difficulty) and dietary regiments (from vegan green cuisine to protein-rich "call of the wild" game entrees).  In March, Red Mountain will open 12 new luxury villas for long-term guests.  DONT MISS the new geo-caching adventure ($50).  This 21st century treasure hunt, which started in the Pacific Northwest two years ago, has a growing global following.  Red Mountain instructors J.P. Paige and Gary Oiler will help you join the chase with a class on navigating by handheld global positioning system device and a strenuous hike on sandy trails to locate a nearby cache containing a logbook.
