Mount Rainier requires chains in every vehicle from November 1, and there is no vehicle camping all winter

From November 1 to May 1, every vehicle in Mount Rainier National Park has to carry tire chains, and that includes 4WD and AWD. Pair that with the other winter fact: there is nowhere in the park to sleep in a vehicle until spring. If you drive a van or an RV, Rainier is a day trip from now on. Both checked October 27, 2026.

The chain rule

The park’s Tire Chain FAQ says all vehicles must carry “tire chains or state-approved alternative traction devices at all times” between November 1 and May 1, “regardless of tire type or weather conditions.” Sunny days and rental cars count.

Before you buy:

• Autosocks are allowed for passenger vehicles under 10,000 pounds.
• If your owner’s manual warns against chains, the park points you to cable chains made for low-clearance vehicles.
• In its summary of Washington’s rule, the FAQ adds that vehicles over 10,000 pounds must carry a second set of chains. Heavier motorhomes, read that line.

There is no gas in the park, and the park says to buy chains before you come and practice putting them on.

Where you can sleep: nowhere with wheels

All three auto campgrounds are closed. Cougar Rock and White River are closed for the season, and Ohanapecosh stays closed through 2026 for construction, according to the hours page updated October 23. The winter recreation page is blunt: “No vehicle camping is available anywhere in the park during the winter season.” The campground regulations also say sleeping in vehicles outside campgrounds is not permitted.

Snow camping is the only overnight option, and it is not open yet. The park’s October 19 update says winter camping at Paradise is closed until the snowpack builds. Paradise needs at least five feet of snow. Mazama Ridge, Reflection Lakes and other areas need at least two. The winter camping page says that typically starts in January and ends May 15. Every overnight needs a wilderness permit; for the Paradise side, you get it in person at Longmire. Camp at least 300 feet from plowed roads, parking areas, trails and buildings, and 100 feet from water. Campfires are prohibited; stoves are fine.

The gate that strands people

Once winter schedules start, the gate at Longmire closes every night while crews assess the Paradise road. The winter travel page gives the typical schedule as opening at 9 a.m., closing to uphill traffic at 4 p.m. and to downhill traffic at 5 p.m., and it recommends leaving Paradise by 4:30. It can open late or not at all. On October 26 the gate was already closed overnight.

Winter vehicle access is the Nisqually Entrance only. The road status page lists Stevens Canyon, Sunrise and Paradise Valley roads closed for the season, with SR 123 and SR 410 expected to close in mid to late November.

What to do

Put chains in the vehicle before November 1, not the morning you drive up. Book your night outside the park and treat Paradise as a round trip you finish by 4:30. Check the park’s alerts after 4 p.m. the day before, and again after 7 a.m., for the gate forecast.
