Direct answer: Every vehicle entering Mount Rainier National Park must carry tire chains or approved alternative traction devices from November 1 through May 1. The requirement applies even to all-wheel-drive and four-wheel-drive vehicles and even when roads appear clear. home.nps.gov
Carry the correct equipment
Do not interpret “chains required” as meaning they are needed only during active snowfall. The National Park Service requires visitors to carry them throughout the winter season.
Before traveling:
- Confirm that the chains fit your tires.
- Read the manufacturer’s instructions.
- Practice installing them somewhere dry and safe.
- Pack waterproof gloves and a kneeling pad.
- Check whether a rental-car agreement restricts chain use.
Approved alternative traction devices may satisfy the carrying requirement, but travelers should verify that a particular device meets Washington and park rules.
Understand winter road access
Mount Rainier remains open year-round, but winter access is limited. The Nisqually Entrance in the park’s southwest corner provides access toward Longmire and Paradise. Other entrances and roads generally close seasonally. nps.gov
The road from Longmire to Paradise closes nightly during the winter operating period. Weather, staffing, plowing, avalanche risk, and vehicle incidents can also delay its morning opening or prevent it from opening at all. nps.gov
Check the official road-status page on the morning of the visit. An old social-media post or navigation app cannot confirm that a gate is currently open.
Keep your itinerary flexible
Create two versions of the day:
Plan A: Visit Paradise if the road is open and conditions are manageable.
Plan B: Spend time around Longmire or postpone the mountain drive if upper-road access is unavailable.
Do not wait at a closed gate in a location where your vehicle obstructs snow-removal work. Follow ranger directions and turn around when advised.
Winter daylight is limited, so choose a conservative return time. A sunny afternoon can turn into icy evening driving once temperatures fall.
Prepare beyond the chain requirement
Bring warm layers, waterproof boots, food, water, a flashlight, a charged phone, and basic emergency supplies. Download the park map before entering areas with unreliable service.
Snow-covered terrain can conceal streams, steep drops, and trail markers. Visitors unfamiliar with winter navigation should stay in established areas and consider ranger-led activities when available.
Takeaway: Carry properly fitting chains, confirm the road status that morning, and treat Paradise as conditional rather than guaranteed.
