What to Expect

This is the big one — 93 miles of pure circumnavigation around the most glaciated peak in the Lower 48. The Wonderland Trail is less a hike and more a multi-day expedition that strings together every ecosystem Rainier has to offer: old-growth forest draped in moss, alpine meadows exploding with lupine and paintbrush, glacial river crossings that'll wake you up faster than any coffee, and high passes where the mountain fills your entire field of vision. You'll gain and lose roughly 22,000 feet of elevation over the full loop — think climbing and descending the equivalent of a couple fourteeners back-to-back-to-back. The trail rolls through deep valleys and exposed ridgelines, alternating between cathedral-like forest canopy and wide-open volcanic terrain. This one belongs to backpackers who want the definitive Rainier experience and have ten days to prove it.

Safety Advisory

Glacial river crossings are the real hazard here — Tahoma Creek, Carbon River, and Winthrop Creek can run thigh-deep by afternoon on hot days. Cross in the morning when snowmelt volume is lowest, unbuckle your hip belt, and use trekking poles for stability.

Weather on Rainier shifts without warning. You can start a pass in sunshine and be in a whiteout thirty minutes later. Carry layers for near-freezing temps even in August, and pack a full rain setup — the mountain makes its own weather.

Snow lingers on Panhandle Gap and Indian Bar well into late July some years. Check ranger station conditions reports the week before your start date. Microspikes and an ice axe are worth the weight if the snowpack is above average.

Pro Tips

Trail Tip

The wilderness permit lottery opens March 15 — set a calendar reminder and apply the first day. Walk-up permits exist but you'll be building your itinerary around whatever campsites are left, which usually means brutal mileage days.

Trail Tip

Cache food at designated ranger stations (Mowich Lake, White River, Longmire) to avoid hauling ten days of supplies from the start. Submit a food cache request with your permit application — they fill up fast.

Trail Tip

Start at Longmire or Mowich Lake and go clockwise. You'll hit the exposed northern sections while your legs are still fresh, and the final stretch through the Carbon River valley is a forested, gentle finish that feels like a reward.
