The 37th Street Trailhead was added to the Apple Capital Loop Trail in the summer of 2009. The parking lot is north of US Highway 2 and east of the Columbia River. It can be reached off of Cascade Avenue by traffic traveling westbound on the highway.
Prior to the building of the 37th Street Trailhead, formal access to the Apple Capital Loop Trail from the Douglas County side was only available further south. With pedestrians and bike riders crossing the busy highway to get to the trail, a solution was needed and this new trailhead was the result.
Once you leave the 37th Street Trailhead parking lot you head down a somewhat steep grade and follow the paved trail beneath the Odabashian Bridge. It crosses a small creek and loops up on the other side to connect to the loop trail where you can go right and head south towards East Wenatchee or left and head north up to the crossing of the bridge.
The 37th Street Trailhead gets a little less attention than other more popular trail access points, but that could also change as the proposed Rocky Reach Trail that is proposed to extend from there all the way up past Rocky Reach Dam and to Lincoln Rock State Park becomes more and more of a reality.
