Situated in Southern Colorado, the Great Sand Dunes National Park is an impressive sight. Shaped by winds blowing from and against the nearby Sangre de Cristo Mountains, the piles of sand climb to more than 750 feet (230 meters), making them the tallest dunes in North America. Sand-boarding, skiing and sledding on the dunes are the park’s most popular activities, and there are medium-size slopes to slide on located near the main parking area. A longer hike to the north brings thrill seekers to a 300-foot (90 meter) slope that tumbles onto into Medano Creek.

Mesa Verde was home to the Ancestral Pueblo who inhabited the dwellings from approximately 600 AD to 1300 AD.

A number of hiking trails, which do not require a ranger tour, lead to lookouts and interesting sites, including petroglyphs.
