Rocky Mountain National Park

Rocky Mountain National Park encompasses 415 square miles of rugged alpine scenery in north-central Colorado, straddling the Continental Divide at elevations ranging from 7,860 to 14,259 feet. The park protects one of the most ecologically diverse landscapes in the American West, where visitors can traverse meadows filled with wildflowers at lower elevations, pass through subalpine forests of Engelmann spruce and subalpine fir, and emerge onto vast expanses of treeless tundra that account for roughly one-third of the park's total area.

Trail Ridge Road, the park's signature drive, climbs to 12,183 feet making it the highest continuous paved road in the United States. Open from late May through mid-October, the road crosses alpine tundra for 11 miles, offering sweeping panoramas of the Front Range and the Kawuneeche Valley on the western slope. Multiple pullouts and short interpretive walks let visitors explore the delicate tundra ecosystem without venturing far from their vehicles.

Wildlife is abundant and frequently visible. Elk are the park's most iconic residents, with herds of several hundred animals moving through meadows at Moraine Park, Horseshoe Park, and Kawuneeche Valley. During the fall rut in September and October, bull elk can be seen bugling and sparring for dominance — one of the most dramatic wildlife spectacles in North America. Rocky Mountain bighorn sheep frequent the Horseshoe Park area, while moose are found in willow thickets along the North Fork and around Kawuneeche Valley on the western side of the park.

The park's 350-plus miles of maintained trails range from easy paved paths to challenging routes ascending multiple fourteeners. The Bear Lake area is the most visited, where interconnecting trails lead to Dream Lake, Emerald Lake, and Nymph Lake in under five miles round-trip. For solitude, wilderness areas on the north and east flanks see far fewer visitors. The Longs Peak summit trail — a 14.5-mile round trip with over 5,000 feet of elevation gain — is Colorado's most-climbed fourteener, typically attempted from midnight to beat afternoon lightning.

Visitor infrastructure is concentrated at the Fall River and Beaver Meadows entrances near Estes Park on the east side, and the Grand Lake entrance on the western slope. The Beaver Meadows Visitor Center offers exhibits on geology, ecology, and park history. Timed-entry permits are required for the most popular areas from late May through mid-October, with reservations opening months in advance on recreation.gov. A $35 vehicle fee covers seven days of access; annual America the Beautiful passes are accepted.
