About camping in Mount Rainier National Park
Mount Rainier rises to 4,392 m above Washington's Cascades, and its glaciers make their own weather. Campgrounds sit on the lower forested flanks — Cougar Rock near Longmire and Paradise, Ohanapecosh in old-growth on the south-east side, White River below Sunrise — with wilderness camps along the Wonderland Trail by permit. Cloud wrapped around the mountain can mean drizzle at camp while the summit is clear, or the reverse. This page is a live Mount Rainier camping go/no-go — not a reservation system.
Best time for camping in Mount Rainier National Park
Mid-July through September is the core season: roads to Paradise and Sunrise are open, wildflower meadows peak in late July and August, and the weather is most settled. Higher campgrounds such as White River open later once snow clears. June can still hold deep snow at upper trailheads, and October brings the rain back.
Where to camp in Mount Rainier National Park
- Cougar Rock — south side, between Longmire and Paradise
- Ohanapecosh — south-east side, in old-growth forest by the river
- White River — north-east side below Sunrise; opens later in the season
- Mowich Lake — small walk-in campground in the north-west

Mount Rainier National Park camping weather and conditions
Rain and low cloud are the default for much of the year west of the Cascades. A lenticular cloud cap over the summit often signals incoming weather. Glacier-fed rivers rise on warm afternoons, and river valleys carry lahar and debris-flow hazards. Late-summer wildfire smoke can drift in from the east.
