Rocky Mountain National Park’s 2026 Timed Entry System Begins May 22

Reservations are already on sale. Trail Ridge Road's opening is still weather-dependent. And the park is operating with significantly fewer staff than it had a year ago. Here's what every visitor should know before heading up.

Estes Park, CO — Rocky Mountain National Park's 2026 timed-entry reservation system begins Friday, May 22, and runs through mid-October, the National Park Service confirmed in its February announcement. If you're planning to visit between now and Memorial Day weekend, the next two weeks are going to be busy — and not just for visitors.

Reservations have been on sale through Recreation.gov since May 1. Trail Ridge Road, the iconic 48-mile route across the park, is still being plowed. And RMNP — like every national park in the country — is heading into the 2026 season with a smaller permanent workforce than it had a year ago. If you've never visited the park during the busy season, or if it's been a few years, the system you'll encounter this summer is more structured than it used to be. Here's what you need to know to plan a smart, safe, and respectful trip.

Two reservation types, two different windows

The 2026 system is essentially identical to 2025, with two reservation types you can choose from:

Timed Entry + Bear Lake Road is required if you want to access the Bear Lake Road Corridor — which includes Bear Lake itself, Glacier Gorge Trailhead, Bierstadt Lake, Sprague Lake, and several of the park's most photographed destinations. This reservation is required between 5 a.m. and 6 p.m. daily from May 22 through Sunday, October 18, 2026. This is the permit that sells out the fastest, and it's the one most first-time visitors want.

Timed Entry (without Bear Lake) gives you access to the rest of the park, including Trail Ridge Road, the Alpine Visitor Center, the west side via Grand Lake, Wild Basin, and Lily Lake. The reservation period for this permit runs from 9 a.m. to 2 p.m. The "rest of park" reservation requirement ends October 13.

Both permits get you a two-hour entry window. Once you're in the park, there's no required departure time — you can stay as long as you want. The only cost is a $2 processing fee on Recreation.gov, on top of the standard park entrance fee ($30 for a 7-day vehicle pass, or free if you have an America the Beautiful pass).

How to actually get a reservation

The reservations are released in monthly batches:

• May 1: Dates from May 22 through June 30 (already released)
• June 1: July, plus any leftover June dates
• July 1: August, plus any leftover July dates
• August 1: September, plus any leftover August dates
• September 1: October, plus any leftover September dates

There's also a daily release of additional permits at 7 p.m. the night before the desired entry date. If your first attempt struck out, this is your second-best shot.

A few hard-won tips from years of watching the system: Set a calendar reminder for monthly release days at 7:59 a.m. MT. Have your Recreation.gov account already created, logged in, and your payment info saved. Know which trailhead you want before you start — fumbling through the map costs you the window. And weekday mornings see far less competition for permits than Saturday morning slots.

If you miss out entirely, you have one more option: arrive before the window starts. You can enter the Bear Lake Corridor before 5 a.m. or the rest of the park before 9 a.m. without a reservation. You'll just have to commit to a very early alarm.

What about Trail Ridge Road?

Trail Ridge Road is the highest continuously paved road in the United States, topping out at 12,183 feet across 48 miles between Estes Park and Grand Lake. About 11 of those miles sit above tree line, which is why it can't operate as an all-season road — winds regularly exceed 100 mph at the high points, and drifts can pile 20 feet deep against the road.

As of mid-May, plow operators are still working. The park's official position is that they're "working toward opening the road on Friday, May 22, but we'll see what the next week brings."

That's the honest answer. Trail Ridge Road normally opens to through travel during the last week in May, weather permitting — in 2025, it opened on Friday, May 30. The earliest opening on record was May 14, 2012, during a historic drought year.

This year is also a drought year — a more severe one than 2012. Colorado's peak snowpack in 2026 set a new benchmark low, the lowest since SNOTEL monitoring began. In theory, that should make plowing easier. In practice, May storms still happen, and last week's spring snow dropped fresh accumulation across the park. I'd plan as if Trail Ridge will open on schedule but be ready to adjust if a late-May storm pushes things back by a few days.

Old Fall River Road, the one-way scenic gravel route up from Endovalley to Fall River Pass, doesn't typically open until early July, so don't plan on it for a spring visit.

Conditions you need to know about

Even after Trail Ridge opens, the high country is going to feel very much like winter. RMNP rangers reported snow on most trails above 9,000 feet earlier in May, and a single storm dropped 19 inches of fresh snow at Bear Lake. Glissade tracks have been spotted on steep slopes near Chasm Junction below Longs Peak.

For anyone hiking outside the paved areas in May or June, that means:

• Microspikes are not optional for higher-elevation trails. North-facing slopes and shaded sections will hold snow well into June.
• Snow conditions change by the hour. Morning ice can become afternoon slush — and unstable, wet snow above tree line means real avalanche risk on steeper terrain.
• Trails like Flattop Mountain, Sky Pond, and Chasm Lake still have meaningful snow above tree line. Don't underestimate them just because the lower miles are dry.
• Stream crossings will run hard. Even with reduced snowpack, the snow that's melting is going somewhere — fast.

If you're thinking about climbing Longs Peak, the only fourteener inside the park, the technical winter route is still in play through at least early July most years. Our Longs Peak route guide covers the full picture, and you should not attempt the Keyhole Route until summer conditions arrive.

The bigger picture: a park with less margin

There's one piece of context most coverage of RMNP's 2026 season is glossing over. The National Park Service has lost roughly 24% of its permanent staff since early 2025, on top of a 20% reduction over the prior decade. Rocky Mountain National Park has been operating with reduced staff capacity throughout 2025, with the Department of the Interior issuing a secretarial order requiring all parks to "remain open and accessible" regardless of staffing levels.

Visitors who came through last summer mostly reported the park looking normal. But anonymous rangers told Outside magazine and other outlets that the appearance of normalcy was the result of remaining staff being stretched far beyond a sustainable pace. Search and rescue operations, in particular, take significant staff time, risk, and emotional energy — and every SAR mission in 2026 will be drawn from a smaller pool than the park had two years ago.

That doesn't mean don't visit. Rocky Mountain National Park is one of the great wonders of this country, and your entrance fees and visitor presence support the case for keeping these places funded and protected. But it does mean that how you visit matters more than ever:

• Pack out everything. Trash service is stretched thin.
• Stay on designated trails. Recovery from off-trail damage takes years of staff time that isn't available.
• Be honest about your experience and fitness. A botched route choice or an unprepared hiker who needs SAR is now drawing from a much smaller team.
• Be patient. Lines at entrance stations, longer waits at visitor centers, slower response times — these aren't anyone's fault. They're the math of fewer staff and the same visitor volume.

This is the moment when Leave No Trace stops being an abstract set of principles and starts being a concrete act of solidarity with the people working to keep the park functioning. Plan ahead. Know before you go. Pack the Ten Essentials. Don't take risks that would cost a stretched-thin SAR team a 14-hour mission.

What to do this week

Rocky Mountain National Park sees more than 4 million visitors a year, and it earns every one of them. With the right plan — and the right respect for what the park's smaller team is up against this year — your 2026 visit can be one of the best trips you'll take.

The mountains will be here. So will the park. Let's all do our part to keep it that way.
