What you are applying for
The Wonderland Trail circles Mount Rainier in 93 miles, and the Park Service puts the climbing at about 27,000 feet, with the same again in descent, because the route repeatedly drops into river valleys and climbs back onto the ridges between them. You will still see 22,000 quoted very widely; that is the older figure, and the higher one is what the managing agency now publishes. Most people take nine to thirteen days. It is not technical at any point, but the cumulative climbing is what people underestimate.
The permit is not for the trail. It is for a specific campsite on a specific night, for every night of your walk, and it has to describe a route that works: consecutive camps you can actually get between in a day. That is why the application is harder than a normal lottery entry, and why a lot of entries fail on the itinerary rather than on luck.
The three ways on
- The early-access lottery. Runs in late winter. Winners get a time slot to make their reservation, not the reservation itself, so a winning entry still means competing for the specific camps you want when your slot opens. Odds sit in the region of 4 to 6 percent.
- General reservations. Open in spring, after the lottery slots have run. What is left is real but thin, and it moves fast. This is worth watching even if the lottery has already disappointed you, because cancellations surface here.
- Walk-up permits. A share of every campsite is held back from the reservation system entirely and issued in person, a short window ahead of the date, at the wilderness information centres. This is the route almost nobody plans for and the one that quietly works.
How the walk-up route actually works
Turning up and asking for a permit sounds like a long shot, and for a specific nine-day itinerary starting tomorrow it is. What makes it work is flexibility. If you arrive with a rough plan rather than a fixed one, are willing to walk the loop in either direction, and can start on any of three or four days, a ranger can usually build you something.
The people who succeed at this arrive early in the day at a wilderness information centre, have a list of acceptable camps rather than one plan, and have food for the whole loop already in the car so they can start the same day. The people who fail arrive at four in the afternoon wanting one specific itinerary.
Be aware that this means a genuinely different trip. You may walk the loop anticlockwise when you meant to go clockwise, or do a longer day in the middle than you would have chosen. On a nine-day walk around a mountain, that matters less than it sounds.
Section hiking, which nobody regrets
The loop is not an all-or-nothing proposition, and the permit pressure is very unevenly distributed. A three or four night permit for a single section is far easier to get than a full circuit, and the southern leg past Indian Bar, reached from Box Canyon or Fryingpan Creek, is the one people remember most.
One important caveat on where you start. Mowich Lake and Carbon River currently have no road access. The SR 165 Fairfax Bridge closed permanently in April 2025 to vehicles, bicycles and pedestrians alike, with no alternate route, and access is not expected to be restored for years. Plenty of older guides and trip reports still treat Mowich Lake as a trailhead or a resupply point. It is neither at the moment: that corner of the park can only be reached on foot from elsewhere inside it, on a wilderness permit. Plan any section around the Nisqually, Stevens Canyon or White River entrances instead.
If this is your first long walk in the park, a section is also the honest recommendation. You find out how your body handles repeated 3,000-foot climbs with a full pack before you commit to doing it eleven more times.

Timing and snow
The trail is normally walkable from mid-July to late September, and the constraint at both ends is snow on the high passes rather than the calendar. In a heavy snow year the high sections can be under snow well into July, which makes some camps unusable and some crossings genuinely hazardous. In a light year, late June is sometimes possible.
Late September is the quiet, beautiful window: the huckleberries have turned, the crowds have gone and the light is low. It is also when the first serious weather arrives, and the days are short enough to matter on the longer legs.
Check the park's current snow conditions before you finalise an itinerary, because a camp that looks reasonable on the map may be unreachable in the week you have chosen.
Food caches
You do not have to carry eleven days of food. The park allows caches at Longmire Wilderness Information Center and White River Campground, which you drop off yourself before you start, and nearly everybody walking the full loop uses at least one. Planning your itinerary around a cache point is one of the few things that makes the permit application easier rather than harder, because it gives you more acceptable camp combinations.
Note that caching at Mowich Lake is suspended, and caches sent to Carbon River cannot be returned, because the Fairfax Bridge closure has cut vehicle access to that whole corner of the park. Any itinerary or packing list that still lists Mowich as a cache point predates the closure.
Wonderland Trail Permits FAQs
The early-access lottery awards roughly 4 to 6 percent of entries. General reservations in spring and walk-up permits issued in person are the other two routes, and between them they account for how most people actually get on the trail.
93 miles around Mount Rainier, with about 27,000 feet of total climbing according to the Park Service. Most people take nine to thirteen days.
Yes. A share of every campsite is held back from the reservation system and issued as first-come walk-up permits at the wilderness information centres. Arriving early, being flexible on direction and start date, and having a list of acceptable camps rather than one fixed plan is what makes it work.
Mid-July to late September. The limit at both ends is snow on the high passes rather than the date. Late September is quieter and more beautiful but brings shorter days and the first autumn weather.
Yes. The permit reserves a specific campsite for each night of your trip, and the itinerary has to consist of camps you can realistically walk between in a day.
Yes, at Longmire Wilderness Information Center and White River Campground, which you drop off yourself before starting. Nearly everyone walking the full loop uses at least one. Caching at Mowich Lake is currently suspended because the Fairfax Bridge closure has cut road access to that side of the park, and caches sent to Carbon River cannot be returned.
Considerably. A three or four night permit for a single section is far easier to get than a full circuit, and the southern leg past Indian Bar is the most rewarding. Note that Mowich Lake and Carbon River have had no road access since the SR 165 Fairfax Bridge closed permanently in April 2025, so plan a section from the Nisqually, Stevens Canyon or White River entrances instead.
The Park Service puts it at about 27,000 feet of gain and the same in loss across the full loop. An older figure of 22,000 feet is still widely repeated elsewhere. The trail repeatedly drops into river valleys and climbs back onto the ridges between them, which is what people underestimate rather than the mileage.
