Ever tried SUP'ing? This may be the "It" sport these days, but that's because it's fun and a full-body challenge all at once, which is why Olympic decathlete Trey Hardee calls it his favorite active-rest sport. Kodi Rafting in Frisco (Summit County) offers half-day, full-day, and overnight trips, in addition to a full-day SUP'ing trip for $156, which includes gear rental, transportation, and lunch.
Voted the No. 1 Hottest Spot to Cool Off by the Travel Channel, Colorado's got you covered. Try Breckenridge Whitewater Rafting, which offers great buy-one-get-one-50%-off deals, or Raft Colorado for experienced rafting guides in Breck, Steamboat Springs, Winter Park, and Vail, too. For scenic floating or Class V challenges, Colorado outfitters can take you down the Arkansas River at the Royal Gorge, Eagle Creek, or the Colorado River.
Crested Butte, CO, is considered the birthplace of mountain biking, so Butte and Winter Park are stupendous destinations, like the famous Trail 401. Other favorite MB singletracks include Buffalo Creek (in Pine), an intermediate 14-miler; Monarch Crest, an advanced 32-miler in Salida; and 18 Roads, a 40-mile network of easy to expert routes in Fruita. Bonus: In towns like Telluride and Steamboat, the gondolas take you straight to the top (for free in Telluride)!
Go paragliding in Telluride. Nestled in a box canyon more than 8,500 feet above sea level, Telluride is the perfect setting for air sports. Telluride Airforce launches straight from Gold Hill at 12,250 feet and lands in town at 8,750 feet.
