You have to have a yearly pass to be there which costs $30 i think
Depennds some times the places wre reserver but there is usally a spot open qnd u hal to hqve one or those passes ror the park
I'm not 100% sure but to reserve an area cost different than having the Discovery Pass OR renting the area on the day you want to use it
WA does an annual pass system. Or pay as you go. If you reserve a site, you don't have to pay the fee or have the pass. If you have a big crew coming, probably best to call the rangers. They were super friendly and helpful to this (way) out-of-towner.
As a state park, there is a daily user fee of $10.00. There are large picnic areas that would need reservations. Smaller single user no.
