Rocky Mountain National Park

Rocky Mountain National Park covers 415 square miles of the Front Range in northern Colorado, astride the Continental Divide. It climbs from 7,600 feet in its valleys to 14,259 feet on Longs Peak. It was established on 26 January 1915, and in 2025 it had 4,171,431 recreation visits, the sixth most of any national park. A third of it is alpine tundra, crossed by the highest paved through road in the country.

The park is a short drive from Denver, which is why it fills up and why it rations entry in summer. We checked every figure below on 27 October 2026 on the park's own pages, Recreation.gov and NOAA's normals.

Do you need a timed-entry permit for Rocky Mountain?

Rocky Mountain requires a timed-entry permit in the busy season, on top of the entrance pass. In 2026 there were two, both booked on Recreation.gov for a $2 fee per vehicle. Each gives a two-hour window to enter, with no set time to leave:

• Timed Entry: the whole park except the Bear Lake Road corridor, from 9 a.m. to 2 p.m. daily, 22 May to 12 October.
• Timed Entry + Bear Lake Road: the corridor to Bear Lake, Moraine Park and Glacier Gorge, plus the rest of the park, from 5 a.m. to 6 p.m. daily, 22 May to 18 October.

Permits are released at 8 a.m. Mountain Time on the first of each month for the month ahead, and 40% of each day's permits go on sale at 7 p.m. the evening before. They are not sold at the entrances. Entering before 9 a.m. or after 2 p.m., or before 5 a.m. or after 6 p.m. for Bear Lake Road, needs no permit.

Since 19 October 2026 no permit has been needed, only the pass. The park had not announced its 2027 system by 27 October.

What does Rocky Mountain charge for a day or a week?

Rocky Mountain sells a one-day pass as well as the usual seven-day one. A car pays $30 for a day or $35 for a week, a motorcycle $25 or $30, and a person on foot or bicycle $15 or $20. Children under 16 enter free, and a pass is needed at every hour of the day, all year.

Rocky Mountain is one of the eleven parks with a $100 surcharge in 2026 for every non-resident aged 16 or over. Two adults from abroad in one car pay $230 for a day or $235 for a week, and the $250 non-resident America the Beautiful pass covers it all.

The three entrance stations take cards only. Visitors with cash can buy most passes at the Conservancy shops in the Beaver Meadows, Fall River and Kawuneeche visitor centres. Our guide to national park fees for international visitors explains how to buy a pass in advance.

When is Trail Ridge Road open?

Trail Ridge Road crosses the park for 48 miles between Estes Park and Grand Lake. The Park Service calls it the highest continuous paved road in the United States. It tops out at 12,183 feet, with eleven miles above 11,500 feet, few guard rails and no shoulders.

The road usually opens to through traffic in the last week of May and closes for the winter from mid-October. In 2025 it opened on 30 May and closed on 14 November, and in 2026 it opened on 29 May.

On 27 October 2026 the park's alert said it had closed at 5 p.m. on 23 October for snow, at Many Parks Curve on the east side and the Colorado River Trailhead on the west, without saying whether for the season.

The Alpine Visitor Center at Fall River Pass, 11,796 feet up, is the highest visitor centre in the national park system, usually open from May to October. Old Fall River Road, the original 9.4-mile gravel road up to it, runs one way uphill from early July to early October. It closed to cars for the season in October 2026 and stays open to walkers, cyclists and leashed dogs through the winter.

What is in the Bear Lake corridor?

The Bear Lake Road corridor holds most of the park's best-known lakes and trailheads, along a paved road of 9.2 miles that stays open all year. It climbs from the Beaver Meadows Entrance to Bear Lake at 9,475 feet, past Moraine Park, Sprague Lake and the Glacier Gorge Trailhead.

The Bear Lake car park is often full by 9 a.m. all year, and Glacier Gorge fills earlier. From 22 May to 18 October 2026 a free shuttle ran every 10 to 15 minutes to Bear Lake from a Park & Ride about five miles up the road.

A Hiker Shuttle, at $2 a booking for up to four tickets, ran from the Estes Park Visitor Center. No shuttle runs in winter, on Trail Ridge Road or on the west side.

Which Rocky Mountain trails start at Bear Lake and Glacier Gorge?

Rocky Mountain's classic day hikes start at the Bear Lake and Glacier Gorge trailheads, already above 9,000 feet. The distances below are the Park Service's, one way.

Snow covers the Bear Lake Trail from late October to early June, so the Park Service advises traction devices and waterproof boots then. Longs Peak by the Keyhole Route is 15 miles there and back and takes 10 to 15 hours, and the park says it is not a hike. Since 18 October 2026 it has carried a winter advisory expected to last into June 2027.

How do you cope with the altitude and the afternoon storms?

Estes Park itself sits at 7,500 feet, and the trailheads and Trail Ridge Road are far higher, so altitude sickness can reach anyone. The Park Service says fitness plays no part. Its symptoms are headache, loss of appetite, nausea, weakness or dizziness, and the only cure is to go down.

Thunderstorms mostly build after noon in summer, so the Park Service advises starting summit hikes early in the morning and staying off the open tundra when clouds gather. Keep at least 75 feet, two bus lengths, from elk and bighorn sheep.

Where can you watch the elk rut?

Elk gather in the park's meadows every autumn for the rut, when bulls bugle and herd their cows. Moraine Park and Horseshoe Park are the easiest places to watch from a road. The Park Service counts 200 to 300 elk wintering in the park and 400 to 500 more in the town of Estes Park.

During the rut, Moraine Park, Horseshoe Park, Upper Beaver Meadows, Harbison Meadow and Holzwarth Meadow close to foot travel off roads and trails from 5 p.m. to 10 a.m. In 2025 the closures ran from 1 September to 31 October. Calling elk or shining lights at them is illegal.

Where do you sleep near Rocky Mountain?

Rocky Mountain has no hotels or lodges inside the park, so visitors sleep in Estes Park on the east side or Grand Lake on the west. The park's own beds are campsites.

In summer, Moraine Park, Glacier Basin, Aspenglen and Timber Creek are booked on Recreation.gov, opening six months ahead, for $35 a night. Moraine Park, with 244 sites, is the largest and the only one open in winter, first come, first served, from 19 October 2026 to mid-May. Timber Creek, the only campground on the west side, closed after 9 August 2026 for sewer work and is due back in summer 2027.

How cold is Estes Park?

Estes Park has mild summers and cold, snowy springs, and April is its snowiest month. The table gives NOAA's 1991 to 2020 normals for the Estes Park 3 SSE station, at 7,812 feet; Trail Ridge Road, more than 4,000 feet higher, is far colder.

Estes Park averages 104 inches of snow a year, and Grand Lake, on the west side, 155. July is the busiest month, and June to September bring 63% of the year's visitors. October, with snow on the peaks and the elk in the meadows, has half July's crowds.

How do you get to Rocky Mountain from Denver?

Denver International is the closest major airport, about 75 miles and an hour and 40 minutes from Estes Park by our own routing. The Park Service says there is no public transport from the airport, though commercial shuttles run to Estes Park.

The Boulder route and the winter route are the park's own figures; the rest are our own routing. On summer weekends from 23 May, Colorado's Bustang bus runs from Denver Union Station to Estes Park for $7.50 one way.

The park is on Mountain Time, and it is one of the places in our guide to Colorado. The other national parks in Colorado are Black Canyon of the Gunnison National Park, Great Sand Dunes National Park and Preserve and Mesa Verde National Park.
