Hike: Wonderland Trail
When to Go: Late July to Mid-September
Round-Trip: 93-Mile Loop, 10 Days
Level: Challenging to Complete the Loop; Moderate for Sections
This circumnavigation of massive Mount Rainier is one of the true epic hikes in the national park system and takes at least 10 days to complete. The Wonderland Trailmakes it possible, with all the marvels of the mighty mountain on vivid display—glaciers and scree fields, high subalpine country with brilliant (some endemic) wildflowers, roaring rivers, and, of course, great looks at the distinguished summit. Eighteen trail camps simplify logistics a bit, but total elevation gain (and loss) is still more than 20,000 feet as the trail undulates over countless Rainier ridges.
