The Wonderland Trail — what it takes
The trail circles the mountain through old growth, subalpine meadows, and glacier-fed valleys, climbing out of every drainage it drops into — about 22,000 feet of gain over the loop. It suits seasoned, fit backpackers ready for two weeks of self-supported mountain miles who can manage food drops and changeable weather. It is not a starter thru-hike.
- Distance 93 mi
- Time 10–14 days
- Permit Wilderness permit (lottery)
- Season Mid-July – Sept
The wilderness permit is the wall — Wonderland itineraries are awarded by an early-spring lottery through recreation.gov, with demand far exceeding supply and a small walk-up share. Then food drops: you ship resupply buckets to ranger stations ahead. And a weather window — the high stretches aren't reliably snow-free until mid-July and can get socked in any time.
The route, in order
How the route runs
Each stop below is a real place on the park's map — walked in sequence, with how long you spend at each.
- Wonderland Trail 10–14 days
The full loop
A continuous circuit of the mountain, most often started and finished at Longmire or Sunrise. There is no shortcut once you're committed — the trail climbs out of every valley it drops into. Plan resupply drops, watch the high passes for snow, and pace the daily mileage to the elevation, not the map distance.
Before you can go
Permit & logistics
A wilderness permit with a set campsite itinerary is required; most are awarded by an early-spring lottery via recreation.gov, with limited walk-up. [VERIFY: current lottery application window, the walk-up share, food-drop rules, and fees against NPS Mount Rainier before publishing.]
Plan B
If conditions turn
A multi-day route has more ways to go wrong than a dayhike. Here is what forecloses it — and your move when it does.
- No lottery permit
Wonderland permits are among the hardest to draw at any national park.
Instead: Try the walk-up permit window in person a day or two ahead with a flexible itinerary, or hike a multi-day section such as Sunrise to Longmire instead of the full loop.
- Early-season snow
The high passes hold snow into July, route-finding over snow gets serious, and bridges over glacial rivers can wash out.
Instead: Aim for late July through September, and check current trail and bridge conditions with the wilderness desk before you start.
