Have you tried Nordic Skiing yet? 

This sport and the availability of trails in and around Park City has grown by leaps and bounds over the last 10 years.  I'm happy to report that there are trails in close proximity to all neighborhoods in Park City and many of these trails are maintained for public use.  We have a family ski pass at White Pine Nordic center as we love their trail system and the world class grooming, however we also frequent the public trails of Round Valley, Utah Olympic Park, and around Snyderville Basin.  Jeremy Ranch has a fun trail on their golf course as well! 

More to come on this sport that offers excellent physical exercise along with another opportunity to be in the beautiful outdoors.
