I was actually going to make a post about this today. Like Joe said, Evans Creek is on national forest land, which means you will need a Northwest Forest Pass (not a Discover).Will I need a forest pass? If so.. One will cover tow rig & jeep...?
They're available from the Chevron in Burnett, which is usually the last stop for gas too. Day passes are ~$5 and a one year pass is $30. One pass will cover both tow rig and Jeep.
I'll also try and get some directions to the campground posted soon for those who aren't familiar with the area.
Sounds like it's going to be a good time!
