Rocky Mountain National Park is one of America's most spectacular national parks — 415 square miles of alpine tundra, dramatic peaks, pristine wilderness, and abundant wildlife just 70 miles from Denver. The park's combination of accessibility (it's one of the closest major national parks to a large metropolitan area) and extraordinary natural beauty makes it one of the most visited parks in the country.

But Rocky Mountain National Park is more than just a day trip from Denver. It's a place of genuine wildness — where elk graze in the meadows, where the alpine tundra stretches to the horizon above treeline, and where the silence of the mountains is broken only by the wind and the calls of birds.

• Elevation range: 7,860 feet (Estes Park) to 14,259 feet (Longs Peak)

Rocky Mountain National Park requires timed entry permits for the most popular areas during peak season (late May through mid-October). Permits are required to enter the park between 9am and 2pm.

Tip: Permits for popular summer weekends sell out within minutes of release. Set an alarm and be ready to book as soon as permits become available.

Trail Ridge Road — US-34 through the park — is the highest continuous paved road in America, crossing the park at elevations above 12,000 feet for more than 11 miles. The road offers spectacular views of the alpine tundra, the surrounding mountains, and the valleys below.

The Drive: The full Trail Ridge Road is 48 miles from Estes Park to Grand Lake. Allow at least 3–4 hours for the drive, with stops at the overlooks and the Alpine Visitor Center.

Alpine Visitor Center (11,796 feet) — the highest visitor center in the National Park System, with exhibits on the alpine tundra ecosystem and spectacular views of the surrounding mountains.

Best Stops:

• Many Parks Curve — a dramatic overlook with views of the park's eastern valleys
• Forest Canyon Overlook — views into the deep Forest Canyon, carved by glaciers
• Tundra Communities Trail — a short, paved trail through the alpine tundra, with interpretive signs explaining the unique ecosystem
• Gore Range Overlook — panoramic views of the Gore Range and the Never Summer Mountains

Season: Trail Ridge Road is typically open from late May through mid-October, depending on snowfall.

Rocky Mountain National Park is one of the finest wildlife watching destinations in the Rocky Mountains, with abundant populations of elk, mule deer, bighorn sheep, moose, and black bears.

The park's elk herd — one of the largest in the country — is the park's most spectacular wildlife attraction. The elk rut (September–October) is the best time to see elk, when the bulls bugle and compete for females in the meadows of Moraine Park and Horseshoe Park.

Best Viewing Spots:

• Moraine Park — the park's largest meadow, with excellent elk viewing year-round
• Horseshoe Park — another excellent meadow for elk viewing, particularly during the rut
• Kawuneeche Valley — the west side of the park, with excellent moose viewing in the willow meadows

Bighorn sheep are commonly seen on the rocky slopes above treeline, particularly along Trail Ridge Road and on the slopes of Specimen Mountain.

Moose are found in the willow meadows of the Kawuneeche Valley on the west side of the park. The best viewing is in the early morning and late evening.

Altitude: The park's elevations range from 7,860 to 14,259 feet. If you're coming from sea level, allow a day or two to acclimatize before attempting strenuous hikes.

Weather: Mountain weather changes quickly. Always bring layers, a rain jacket, and sun protection. Afternoon thunderstorms are common in summer — be off exposed ridges by noon.

Wildlife Safety: Keep a safe distance from all wildlife (at least 75 feet from elk and deer, 300 feet from bears). Never feed wildlife.
