Best Park to Begin a Hike : Boulder’s Chautauqua Park  has a historic theater used for summer music festivals, a restaurant, a playground, and cabins, and is also the starting point for dozens of stellar hikes.
Best Get-Smart Hike : The National Center for Atmospheric Research  has many scientific displays inside, but also offers the Walter Orr Roberts Weather Trail with signs that tell about local weather.
Most Refreshing Hike : The Bluebird Lake Trail  on the south end of Rocky Mountain National Park passes by Ouzel Falls, Ouzel Lake, Calypso Cascades, and Bluebird Lake. Although it can be a difficult hike, it is the perfect respite from a hot summer day in the city.
Best Free Drinks : The Mineral Springs  are one of the best attractions in Manitou Springs. The spring water trickles from decorative spigots and fountains around the historic town. Anyone can bring a cup or bottle and drink as much of the potentially healing waters as they want.
Best Cross-Country Skiing : Devil’s Thumb Ranch , just 15 minutes outside of Winter Park Ski Resort, is a gorgeous and peaceful valley exclusively for cross-country skiing and snowshoeing in winter.
