This trail marks a principal Native American travel route across the Cascades. It is part of the prehistoric Yakama-Cowlitz Trail, which linked people from the Cowlitz Valley with people from the Yakima River drainage. Native Americans using this trail traveled on foot, often carrying trade goods and roots. They later made the crossing on horseback.
Today, as part of the trail system in the William O. Douglas Wilderness, visitors can use this route to create many looping hikes, or out-and-back routes.
This trail begins at Soda Springs trailhead. It winds roughly west to east, through dense forest and subalpine terrain, crosses many small streams, and passing lakes and small potholes as you wind east. The trail crosses the Pacific Crest Trail (PCT) and ends near the Gifford Pinchot National Forest boundary on Tumac Mountain.
