WTA Pro Tip: Save a copy of our directions before you leave! App-based driving directions aren't always accurate and data connections may be unreliable as you drive to the trailhead.

Getting There

From I-90, take Exit 13 and drive south on Lakemont Blvd SE for two and a half miles. Turn left onto SE Cougar Mountain Way and follow the double yellow line. As you drive, the road takes a left, becoming 168th Place SE and then right to become SE 60th Street. Turn off 60th St uphill onto the dead-end road, SE Cougar Mountain Drive.
