Wallace Falls State Park
“Wallace Falls State Park is a 1,380-acre camping park with shoreline on the Wallace River, Wallace Lake, Jay Lake and Shaw Lake. Located on the west side of the Cascades, the park features a 265-foot waterfall, old-growth coniferous forests and fast-moving rivers and streams.”
Here is the Park website. Phone 360-793-0420 Brochure Map
Although the Park touts its ADA trail, neither the brochure nor website say which trail it is. I suspect it is the Small Falls Interpretive Trail 1.5 miles round trip.
