No, you do not need any pass to park here. (The Discover Pass is for state DNR lands and this trailhead is part of the National Forest. And no NW forest pass is required here either: https://www.fs.usda.gov/recarea/giffordpinchot/recarea/?recid=32124 )
You need a NW Forest Pass
You need to buy a Northwest Forest pass to park a vehicle in THIS National Forest.
I believe a Discover pass works? Maybe they are one and the same.
