Is there a fee to go tent camping

Nope. Just fill in the sheet at the front gate after you pick a spot and enjoy! Its a great spot to ride from

"free" as in no daily fee to camp. But you still have to buy a Washington state park discover pass. You can buy a daily pass or but a yearly pass. Much more cost effective to buy a yearly. Purchase anywhere you can buy a fishing license. Fred Meyer or Walmart is where we get them.

Yes free camping. Just need discover pass

So its free camping

As long as you havea Discover Pass, yes.
