Rocky Mountain National Park

Rocky Mountain National Park protects one of the most spectacular high-mountain landscapes in the United States, a 415-square-mile sweep of the Colorado Rockies northwest of Denver where soaring, glacier-carved peaks, alpine tundra, pristine lakes, and montane forests rise to the Continental Divide. With more than 70 peaks above 12,000 feet, crowned by the iconic 14,259-foot Longs Peak, the park is a realm of dramatic alpine grandeur and abundant wildlife.

Its centerpiece is the breathtaking Trail Ridge Road, the highest continuous paved road in the nation, which climbs above 12,000 feet across the tundra, offering sweeping views and an accessible journey into the alpine world above treeline. Below, glacier-sculpted valleys cradle shimmering lakes, wildflower meadows, and rushing streams, while herds of elk (their fall bugling famous), bighorn sheep, moose and marmots roam the high country. With its alpine tundra, towering peaks, scenic road and rich wildlife, Rocky Mountain National Park is a treasured icon of the American high country.

Rocky Mountain National Park offers superb high-country recreation — driving the spectacular Trail Ridge Road above treeline, hiking more than 350 miles of trails to alpine lakes (Bear Lake, Emerald Lake, Sky Pond), wildflower meadows and peaks, climbing Longs Peak and other summits, wildlife watching (especially the famous fall elk rut), backpacking the wilderness, fishing, horseback riding, and winter snowshoeing and skiing. The combination of alpine tundra, towering peaks, glacial lakes, the scenic road and abundant wildlife makes the park a premier and beloved destination in the Colorado Rockies.

Summer (when Trail Ridge Road is open, typically late May to mid-October) is the prime season for the high country, alpine hiking and the road, while fall brings golden aspens and the dramatic, bugling elk rut, a premier time. Spring is variable with lingering snow up high, and winter offers snowshoeing, skiing and quiet beauty (with the high road closed). Timed-entry reservations are required in the busy season. Summer for the alpine, fall for aspens and elk, and winter for solitude are highlights; come prepared for sudden mountain weather and high-altitude effects.

Rocky Mountain National Park’s high country was used for thousands of years by Native peoples, including the Ute and Arapaho, who hunted and crossed the mountains. Drawn by its grandeur, naturalist Enos Mills championed its protection, and the park was established in 1915. The Civilian Conservation Corps later built trails and the engineering marvel of Trail Ridge Road opened the alpine world to visitors. The park preserves the high peaks, the tundra and the valleys, and remains one of the most beloved and visited national parks, a treasured stronghold of the Colorado Rockies.

Rocky Mountain National Park’s dramatic landscape was shaped by ancient mountain-building and, above all, by glaciers. The high peaks, built of ancient rock uplifted as the Rockies rose, were sculpted during the Ice Ages by glaciers that carved the U-shaped valleys, the cirques, the sharp peaks and the basins now cradling the park’s lakes. A few small glaciers and permanent snowfields remain. Above treeline, the alpine tundra spreads across the high, rolling crest along the Continental Divide. The uplifted ancient rock and the glacial sculpting created the park’s soaring peaks, glacial valleys and alpine lakes.

Rocky Mountain National Park is renowned for wildlife — large herds of elk (whose autumn bugling in the meadows is a famous spectacle), bighorn sheep (the park’s symbol) on the high slopes, moose in the willow valleys, mule deer, black bears, coyotes, yellow-bellied marmots and pikas in the tundra, and a rich community of birds. The range from montane forest to alpine tundra creates diverse habitat. The park is an outstanding place for wildlife watching, with the elk rut, the bighorn sheep, and the tundra’s marmots and pikas among the highlights of the Colorado high country.

Rocky Mountain National Park protects a remarkable range of Rocky Mountain ecosystems across its dramatic elevation gradient — montane forests of ponderosa and aspen, subalpine forests of spruce and fir, and, above treeline, the fragile alpine tundra, a rare and delicate ecosystem of low-growing plants adapted to the harsh, cold, windy heights (about a third of the park is tundra). Glacial lakes, wetlands and meadows add habitat. The tundra is especially fragile and slow to recover. Protecting the forests, the tundra, the lakes and the wildlife sustains a globally significant high-mountain ecosystem.

Rocky Mountain National Park holds a treasured place as an icon of the American high country and one of the most beloved national parks, its soaring peaks, alpine tundra, scenic Trail Ridge Road and famous elk embodying the grandeur of the Colorado Rockies. From the Native peoples who crossed its passes to the conservationists who saved it and the millions who visit, the park has become a cherished symbol of mountain wilderness and the alpine world. Rocky Mountain National Park is a defining landmark of Colorado and the American West, treasured for its breathtaking high-country beauty.

Rocky Mountain National Park is in north-central Colorado, with the main gateway town of Estes Park (east side) reached via US-36 and US-34, about 90 minutes from Denver, and Grand Lake on the west side. An entrance fee and, in the busy season, a timed-entry reservation are required. The park offers Trail Ridge Road (seasonal), visitor centers, campgrounds, hundreds of miles of trails, and shuttle services in summer. Trail Ridge Road and high trails close in winter. The high altitude affects visitors. Check the National Park Service for reservations, road status and conditions before visiting.

The National Park Service protects the peaks, the fragile alpine tundra, the forests, the lakes and the wildlife of Rocky Mountain National Park. Visitors help by staying on trails (especially in the fragile, slow-to-recover tundra, where off-trail steps cause lasting damage), never feeding or approaching wildlife (giving elk, moose and bighorn space), packing out everything, protecting water quality, using shuttles to reduce traffic, and following timed-entry and Leave No Trace rules. Protecting the tundra, the forests, the lakes and the wildlife sustains this globally significant and heavily visited high-mountain ecosystem.

Rocky Mountain National Park’s high altitude and mountain weather are serious — visitors from lower elevations may feel altitude sickness, so acclimatize, hydrate, and ascend gradually. Afternoon thunderstorms bring deadly lightning to the exposed high country, so be off peaks and tundra by early afternoon. Carry layers (weather changes fast and snow can fall any month up high), water, and sun protection. Keep your distance from elk, moose and bighorn (especially during the rut). Watch footing on steep, rocky and snowy trails, and respect the altitude, the weather and the wildlife.

An entrance fee and, in the busy season, a timed-entry reservation are required. Stay on trails, especially in the fragile alpine tundra. Never feed or approach wildlife; keep required distances from elk, moose and bighorn. Backcountry camping requires a permit. Camp only in designated areas. Pets are restricted (not allowed on trails). Drones are prohibited. Collecting is prohibited. Pack out all trash. Trail Ridge Road and high areas close seasonally. Check the National Park Service for reservations, permits and current rules before visiting.

The gateway towns of Estes Park (with the historic Stanley Hotel) on the east and Grand Lake on the west lie at the park, with the Roosevelt and Arapaho national forests, the Indian Peaks Wilderness, and the Colorado high country in the surrounding region, and the city of Denver and the Front Range cities about 90 minutes to two hours away. The Continental Divide and the high Rockies define the region. Rocky Mountain National Park anchors a premier high-mountain region of Colorado, a centerpiece of an alpine adventure and a beloved escape from the Front Range cities.

Drive the spectacular Trail Ridge Road (open roughly late May to mid-October) to experience the alpine tundra above treeline, and hike to glacial lakes like Emerald Lake or Sky Pond — but reserve a timed-entry permit in the busy season, start early to beat crowds and afternoon thunderstorms, and acclimatize to the altitude. Watch the famous fall elk rut in the meadows, bring layers for fast-changing weather (and snow any month up high), stay on trails to protect the fragile tundra, keep your distance from wildlife, and use the summer shuttles.
