The Wonderland Trail is one of the most iconic trails in the United States. Over the course of nearly 100 miles, the path climbs and descends through old-growth forests, subalpine meadows bursting with wildflowers, rocky ridgelines with sweeping mountain views, and valleys born of eruption and sculpted by glacial advance and retreat. 

For a decade, Aspire guided runners on a 3-day circumnavigation of Tahoma (Mt. Rainier), tackling the trail in ~30-mile segments each day. In 2025 the Fairfax Bridge closure and the loss of access to the Mowich Lake Campground, became the opportunity for Aspire to re-imagine a grueling 3-day circumambulation, into a more intimate and curated showcase of Tahoma’s wild landscapes. We’re still going deep into pristine trails and hidden corners of the park, but the focus is less on completion and more on the experience of community and the profound sense of awe that Tahoma inspires.

We can’t wait to share this new chapter of Wonderland with you—an experience that celebrates the resilience of the trail, the spirit of those who travel it, and the awe emanating from Tahoma, the Mother of Waters. 

Hike the ups, shuffle the flats, run the downs. Runners average between 3-5 MPH including photo and snack stops.

Runners are NOT required to travel as a group. Pre-trip education and preparation allows runners to travel independently using digital maps, GPX routes, and paper maps for navigation. Aspire guides are on trail in case of emergency.

Pre-requisite (for those running long distance each day): Completion of 50k Distance with 10,000+ feet of elevation gain within 30 days of the trip. We operate on the honor system for this requirement.
