Rocky Mountain National Park was located in the north-central region of the U.S. state of Colorado. Rocky Mountain National Park features royal mountain views, a diversity of wildlife, diverse climates and environments from woody forests to mountain tundra and easy access to back-country trails and campsites. The park is located north-west of Boulder, Colorado in the Colorado Rockies, and includes the Continental Divide and the headwaters of the Colorado River in its land area. The park has five visitor centers. The park headquarters, Beaver Meadows Visitor Center, is a National Historic Landmark, designed by the Frank Lloyd Wright School of Architecture at Taliesin West. The park has three roads, U.S. Highway 34 and 36, and Colorado State Highway 7. State Highway 7 enters the park for less than a mile, where it provides access to the Lily Lake Visitor Center. Highway 36 enters the park on the east side, where it terminates after a few miles at Highway 34. Highway 34, known as Trail Ridge Road through the park, runs from the town of Estes Park, Colorado on the east to Grand Lake, Colorado on the south west. The road reaches 12,183 feet (3,713 m) in elevation, and it is closed in the winter due to snow.
The park is surrounded by Roosevelt National Forest on the north and east, Routt National Forest on the northwest, and Arapaho National Forest on the southwest. Rocky Mountain National Park covers approximately 265,770 acres (1,076 km²) of land in Colorado's northern Front Range. The park is split by the Continental Divide, which gives the eastern and western portions of the park a different character. The east side of the park tends to be drier, with a lot glaciated peaks and cirques. The west side of the park is wetter and lusher, with deep forests dominating. The park contains 359 miles (578 km) of trails, 150 lakes, and 450 miles (720 km) of streams. The park contains over 60 named peaks higher than 12,000 feet (3,700 m), and over one fourth of the park resides above tree line. The highest point of the park is Longs Peak, which rises to 14,259 feet (4,346 m; surveys before 2002 show 14,255 feet (4,345 m) above sea level. Longs Peak is the only fourteen thousand foot peak in the park. Several small glaciers and permanent snowfields are found in the high mountain cirques, including Andrews Glacier, Sprague Glacier, Tyndall Glacier, Taylor Glacier, Rowe Glacier, Mills Glacier, and Moomaw Glacier.
