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

Drive Hwy 20 to the little town of Marblemount. Keep going straight when 20 turns left and you will be on Cascade River Road. Drive the 23 miles to the end. You will follow the Cascade River the whole way; it takes nearly an hour on Cascade River Road.
