Been trying to get clarification on this one... maybe someone out there knows the facts. Does the Vehicle Use Permit exempt one from having to pay the $5 State Park Use Fee that is now posted at most WDFW sites such as Leech Lake???? I haven't been able to find a definitive answer on any website...
Here is your definitive answer. No.
Vehicle Use Permit is only valid on Department of Fish and Wildlife lands.
State Park Use Fee is only valid at State Parks. Mostly sort of.....see link below.
Leech Lake is National Forest. You need a Northwest Forest Pass, or one of the discount passes such as the Access, Senior, or annual pass

Notice that for an extra $20 you get a limited list of Washington state parks where you get to use the pass.
Click on the link. Go through the decision tree. Then go look at the list of Washington and Oregon state parks to see if it is worth upgrading to the $100 pass.
If you are disabled or 62 get one of the federal discount passes. Deal with the rest later.
