Overnight backcountry camping at Mount Rainier National Park requires a wilderness permit issued for specific camp zones or designated sites each night of your trip. Two systems exist: advance reservations through Recreation.gov, which open in mid-March for the full summer season, and walk-up permits available at ranger stations from 7:00 AM daily. The permit costs $8 per person per night plus a $6 non-refundable reservation fee. Popular Wonderland Trail camps — Indian Bar, Summerland, Mystic Lake — sell out within days of the March release. Walk-up permits are genuinely available for most camps mid-week; summer weekend walk-ups require arriving before 7 AM and having flexible itineraries.
How the Wilderness Permit System Works
Mount Rainier's backcountry is divided into designated camp zones and cross-country zones. Most backpackers stay at one of 18 designated camps along the Wonderland Trail or at zone camps accessible from trailheads. Each permit specifies your entry point, the zones or designated camps you'll stay in each night, and your exit point. You can't just camp anywhere — you must have the correct zones on your permit for each night.
The NPS allocates each camp zone's capacity between advance reservations (the majority of spots) and walk-up permits (a portion held back daily). This means that even when advance permits show as sold out on Recreation.gov, walk-up slots exist — you just have to show up in person at a ranger station.
Advance Reservations: The Mid-March Window
Advance wilderness permits open on Recreation.gov in mid-March each year for the upcoming summer season. The exact date varies year to year — check nps.gov/mora each February for the announcement. The release typically happens all at once (not on a rolling 6-month window like front-country campgrounds), so the first days after the release window opens are the most competitive.
Which Camps Sell Out First
| Camp | Elevation | Why It's Popular | Sells Out |
|---|---|---|---|
| Indian Bar ★ | 5,100 ft | Stone shelter, above Ohanapecosh Park; most spectacular Wonderland camp | Hours (peak dates) |
| Summerland ★ | 5,900 ft | Wildflower meadows, glacier views, close to Fryingpan Glacier | Hours (peak dates) |
| Mystic Lake ★ | 5,700 ft | Alpine lake reflecting Rainier, North Park approach | Hours (peak dates) |
| Spray Park ★ | 5,100 ft | Wildflower panoramas, accessible from Mowich Lake | Days (first week) |
| Sunrise Camp | 6,100 ft | Highest Wonderland camp, Burroughs Mountain proximity | Days (first week) |
| Carbon River Camp | 1,700 ft | Old-growth rainforest, lowest Wonderland camp | Days |
| Pyramid Creek | 2,540 ft | Forest camp near Longmire, common trip start | Weeks |
| Maple Creek | 2,720 ft | Forest camp, quieter, good shoulder-season option | Weeks |
Walk-Up Permits: How They Work
A portion of each camp zone's nightly capacity is held back from Recreation.gov and reserved for walk-up permits — permits issued in person at ranger stations starting at 7:00 AM each day for that night's camping. Walk-up permits are not bookable in advance by phone or online; you must appear in person.
Where to get walk-up permits:
- Longmire Wilderness Information Center (WIC): The main permit station. Located at Longmire, open daily in summer starting at 7:00 AM. Issues permits for the entire park. Best starting point for west-side Wonderland Trail sections and Paradise-area trailheads.
- White River Wilderness Information Center (WIC): At the White River Campground turnoff on SR-410. Issues permits for north and east-side trips including Summerland, Sunrise area, and Burroughs Mountain routes.
- Carbon River Ranger Station: At the Carbon River entrance (northwest). Issues permits for Carbon River area and Mowich Lake–accessible routes.
| Day | Walk-Up Availability | Strategy |
|---|---|---|
| Summer weekend (Fri–Sun) | Competitive | Arrive at station by 6:30 AM; have 2–3 itinerary options ready |
| Summer weekday (Mon–Thu) | Good | 7:00 AM arrival usually sufficient; more camp options available |
| Holiday weekends | Very competitive | Arrive by 6:00 AM; be flexible on both dates and camps |
| Shoulder season (May, Oct) | Easy | Walk-up almost always available; check for snow on high camps |
Permit Fees
Wilderness camping at Mount Rainier costs $8 per person per night for all designated camps and cross-country zones, plus a non-refundable $6 reservation fee per permit (not per night). Walk-up permits incur the same nightly fee but the $6 reservation fee may differ — confirm at the station.
| Trip | People | Nights | Camping Fees | Reservation Fee | Total |
|---|---|---|---|---|---|
| Solo overnight | 1 | 1 | $8 | $6 | $14 |
| 2 people, 4 nights | 2 | 4 | $64 | $6 | $70 |
| 4 people, 10-day Wonderland | 4 | 10 | $320 | $6 | $326 |
The $35 park entrance fee is separate and required in addition to permit fees. America the Beautiful pass covers entrance but not permit fees.
Cross-Country Zones: Off-Trail Camping
Experienced off-trail hikers can camp in designated cross-country zones — areas without fixed tent pads where you camp on snow or mineral soil following Leave No Trace principles. Cross-country zone permits follow the same fee structure and are available through the same advance and walk-up channels, but require demonstrated experience with route-finding, self-rescue, and LNT camping. Rangers may ask about your experience at the station. Bear canisters are required in all overnight zones.
Tips for Getting the Permit You Want
- Set a calendar reminder for mid-February to watch nps.gov/mora for the advance permit release date announcement. The window opens in mid-March and the best camps disappear in 48–72 hours
- Have three complete itineraries ready before you log into Recreation.gov — your first choice, a backup route, and a mid-week flexible option. Popular camps on the exact dates you want will be gone; alternatives on adjacent nights often remain
- Check cancellations frequently — especially in the 7 days before a trip date. Cancellations appear instantly on Recreation.gov. Set up alerts if possible
- For walk-ups, be flexible on campsites — rangers will tell you what's available when you arrive. Agreeing to a less-coveted camp is often the difference between getting out and going home
- Mid-week trips are dramatically easier to permit — Thursday arrivals for a Mon–Thu loop, for example, face far less competition for both advance and walk-up slots
- Early and late season (May–June, September–October) have more availability but high camps may have snow; bring microspikes and check conditions at nps.gov/mora
Wonderland Trail Permits
The 93-mile Wonderland Trail circumnavigation of Rainier requires a multi-day backcountry permit specifying each night's camp. You cannot book the entire loop as one permit — you route it camp by camp on Recreation.gov. For full Wonderland Trail itineraries, the 18-campsite breakdown, and resupply logistics, see the Wonderland Trail planning guide.
What to Bring to the Ranger Station for Walk-Up Permits
- Government-issued ID for the permit holder
- Payment (cash or card — confirm station accepts your method)
- Planned itinerary with start point, camps by night, and end point (plus alternates)
- Group size
- Bear canister (required; available to rent at some stations)
