Wyoming Park Road Opening Dates

Name: Seasonal road and facility opening dates for national parks in Wyoming
Creator: National Park Service
License: https://www.usa.gov/government-works

Wyoming is one of the states where the parks publish their dates in advance, so there is something real to plan against. Below: the normal season for every road, entrance, campground and visitor centre the parks here publish one for, drawn on a single calendar; the years of actual opening dates where a park keeps that record; and the link to the page where the park posts today. Every date carries the park's own last-updated stamp, read on 3 September 2026.

Canyon Village to Tower Fall over Dunraven Pass normally opens late May, and the park will not put a date on it any tighter than that

Wyoming, in one paragraph

Canyon Village to Tower Fall over Dunraven Pass normally opens late May.

22 May to 12 October in the 2026 schedule, last to open and first to shut. Wyoming is the state where the openings are a published schedule rather than a guess. Yellowstone posts projected dates for every road segment before the season starts and opens them in waves from mid April to late May, and Grand Teton closes the Teton Park Road on 1 November by rule rather than by snow, partly to leave a corridor for wildlife.

The visual answer

Everything seasonal in Wyoming, on one calendar

Check the park’s own page before you drive. Seasonal roads open when the plows get through and close again for storms, rockfall and fire, sometimes within the same week. What you get here is the normal season for each road and facility in the park’s own words, the years of actual opening dates the parks publish, and a link to the page where that park posts today. Every date on this page shows the park’s own last-updated stamp rather than ours.

Every road, entrance, campground and visitor centre in Wyoming with a published season, ordered by when it normally opens. Bars are the park's own description, not a status and not a forecast. The colour says what governs the date.

These are the dates Yellowstone and Grand Teton published for the 2026 season, read on 3 September 2026. The park says of them: “Roads typically open at 8:00 a.m. on the first day. All dates are subject to change depending on weather conditions.”

“If conditions in Yellowstone are bad enough to require tire chains, we generally close the roads until it is safe to travel.”

11 Wyoming park seasons, and where each one comes from

The last column is the one nobody else shows you: the date the park itself last touched the page each season came from. Read a two-year-old stamp as the park saying nothing has changed, and a stamp from last month as the park saying something has.

Every seasonal road, entrance, campground and visitor centre in Wyoming, ordered by when it normally opens. Each season is the park's own description from the park's own page. None of these is a current status.

Beartooth Highway, US 212, and the Chief Joseph Scenic Byway, WY 296. The Beartooth Highway is not a park road. It runs across Custer Gallatin National Forest between Red Lodge, Montana and the park’s Northeast Entrance, and it is opened and closed by the Montana and Wyoming departments of transportation. Yellowstone publishes the dates because the road is how most people reach Cooke City, and it says plainly to check with MDT and WYDOT before travelling.

Summarised from the state transport departments that run the highways outside park boundaries in our own words.

Where today’s answer lives

Each Wyoming park publishes its own status

Nothing on this site knows what a road is doing this afternoon, and nothing on this site pretends to. Each block below is the park’s own page, with what it carries and the caveats that go with it.

Today’s Yellowstone road status

Yellowstone National Park roads

Published by Yellowstone National Park. It carries a live map of every road segment, the projected opening and closing dates for the season, and the construction delays running at the time you look.

A park road status is rewritten by rangers and road crews inside a day, sometimes inside an hour. Glacier National Park says it about its own map: “This report contains the most recent information available for road, hiker/biker, and entrance closures as well as snowplow status. It may be outdated and inaccurate as our information can change quickly.”

An opening date is the park’s current expectation of when a plow crew will finish or a gate will be unlocked. It is not a promise, it is not a booking, and the parks revise it through the spring as the snow tells them to.

And an open road closes again. Snow falls on high passes in June and September, rockfall shuts a road in an afternoon, wildfire shuts one for a month, and avalanche control closes them on purpose. Glacier’s own record has Logan Pass opening on 21 June 1995 and shut by a rockslide two days later, and opening on 24 May 1980 and closed the next day until 6 June. The link above is the only thing that knows which of those days you are looking at.

Link check: read in a browser on 3 September 2026 and it answered with a page titled for Yellowstone National Park. The park's own stamp on it that day read: last updated September 1, 2026. If it has moved since, Yellowstone National Park is the authority and its own site search is the fastest way back to it.

Today’s Grand Teton road status

Grand Teton National Park roads

Published by Grand Teton National Park. It carries the current status of every park road with the park’s own advisory levels, including the no unnecessary travel and black ice advisories it posts in winter.

Link check: read in a browser on 3 September 2026 and it answered with a page titled for Grand Teton National Park. The park's own stamp on it that day read: last updated September 2, 2026. If it has moved since, Grand Teton National Park is the authority and its own site search is the fastest way back to it.

Common questions

Wyoming park opening FAQ

Is Canyon Village to Tower Fall over Dunraven Pass open right now?

Yellowstone National Park publishes that itself at Yellowstone National Park roads, which carries a live map of every road segment, the projected opening and closing dates for the season, and the construction delays running at the time you look. A road status is rewritten by rangers and road crews inside a day, and Glacier National Park puts it plainly about its own status map: "This report contains the most recent information available for road, hiker/biker, and entrance closures as well as snowplow status. It may be outdated and inaccurate as our information can change quickly." What this page adds is the normal season for every road and facility in Wyoming, the years of actual opening dates where the park publishes them, and the link to the page that has today.

When does Canyon Village to Tower Fall over Dunraven Pass usually open?

What actually closes in Wyoming, and what stays open?

11 road, entrance, campground and visitor centre seasons are covered on this page, across 2 parks: Yellowstone National Park, Grand Teton National Park. 1 of them are open year round and the rest have a season. Wyoming is the state where the openings are a published schedule rather than a guess. Yellowstone posts projected dates for every road segment before the season starts and opens them in waves from mid April to late May, and Grand Teton closes the Teton Park Road on 1 November by rule rather than by snow, partly to leave a corridor for wildlife.

Can a Wyoming park road close again after it opens?

Yes, and several Wyoming roads do every year. An opening is the park saying the road was passable that day, not that it will stay passable. Snow falls on high passes in June and September, rockfall closes a road without warning, and wildfire closes one for weeks. Glacier National Park's own published record shows Logan Pass opening on 21 June 1995 and shutting after a rockslide two days later, and opening on 24 May 1980 and closing the next day in bad weather until 6 June. Only Yellowstone National Park's own status page can tell you which kind of day today is in Wyoming, and the link is above.
