The Front Range is the first mountain range that pops up from the seemingly endless plains of eastern North America. The snowy peaks line the western horizon as seen from the cities of Ft. Collins, Boulder, Denver, and Colorado Springs.
Front Range and Indian Peaks

Rocky Mountain National Park is probably the most famous portion of the Front Range, and sees the majority of Colorado's alpine tourists. The highlight of the park for mountain climbers is Longs Peak, a fourteener that boasts one of Colorado's largest big wall rock faces.
Indian Peaks, part of the Front Range just south of Rocky Mountain National Park, is the range of rugged peaks that rise to the west behind the town of Boulder. There are a few glacial remnants from the "Little Ice Age" several hundred years ago - the southernmost "glaciers" in North America, though they are quickly melting away.
