The Rocky Mountain National Park in the state of Colorado is a sublime sweep of ravishing granite cliffs, pine forests and retreating icefields fringed by starbursts of wildflowers in spring. Spanning 265,461 acres, the park is geologically diverse, with towering mountains descending into dense forests, punctuated by glimmering lakes. The region has been inhabited for over 11,000 years, with the Ute and the Arapaho Tribes being the first to settle around the area. Today, the park features several hiking, biking and winter sports trails, picnic spots, and campsites.
