Chapters · South Washington Cascades
Cowlitz-Naches.
Organizing riders and expanding trail access across the south Washington Cascades.
01 / Regional Overview
Where we ride.
The Cowlitz-Naches chapter spans the south Cascades, covering the Cowlitz Valley, Naches Ranger District, and the trails in and around Mount Rainier's southern flanks.
Signature trail areas include Goat Mountain, the Cispus trail network, Dark Divide, and the Tieton area. The chapter maintains strong relationships with the Gifford Pinchot and Okanogan-Wenatchee National Forests.
Work parties focus on tread sustainability and new trail construction during the short but productive high-country season.
