The Hummocks Trail is about a 2.4 mile loop trail that explores the unique geology of the ever-changing Hummocks area below Mt. St. Helens.
The trail has a number of ups and downs as you pass the many ponds and ash/rock/mud hills (hummocks) on your way towards the North Fork Toutle River. There is abundant wildlife in the area including birds, beaver and elk.
This is also a great place to park and extend your day of hiking on the Boundary Trail towards Johnston Ridge. The Boundary Trail is accessible about 1/2 half mile from the parking lot.
Getting there: From Castle Rock, drive about 45 miles east on Highway 504 toward Johnston Ridge. Just past the Coldwater Lake turn off, turn right into the Hummocks trailhead parking area.
