Rocky Mountain National Park
Rocky Mountain National Park is a national park located in the north-central region of the United States state of Colorado. It features majestic mountain views, a variety of wildlife, varied climates and environments-from wooded forests to mountain tundra-and easy access to back-country trails and campsites. The park is located northwest of Boulder, Colorado, in the Rockies, and includes the Continental Divide and the headwaters of the Colorado River.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.park may be accessed by three roads: United States Highway thirty four, thirty six, and State Highway seven.

Highway thirty six enters the park on the east side, where it terminates after a few miles at Highway thirty four. Highway thirty four, known as Trail Ridge Road through the park, runs from the town of Estes Park on the east to Grand Lake on the southwest. The road reaches an elevation of twelve thousand one hundred and eighty three feet, and is closed by snow in winter.California Zephyr serves Granby (near the west entrance of the park) by rail from Denver, crossing the Continental Divide through the Moffat Tunnel well south of the park.
