Cub Lake, Rocky Mountain National Park

Rocky Mountain National Park is a national park located in the north-central region of the U.S. 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.

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 may be accessed by three roads: U.S. Highway 34, 36, and State Highway 7. Highway 7 enters the park for less than a mile, where it provides access to the Lily Lake Visitor Center which is closed indefinitely. Farther south, spurs from route 7 lead to campgrounds and trail heads around Longs Peak and Wild Basin. 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 on the east to Grand Lake on the southwest. The road reaches an elevation of 12,183 feet (3,713 m), and is closed by snow in winter.
