During peak season at Washington State parks, you're able to stay up to 10 nights at a time. During off-peak times it is 20 nights. That being said, you're also not allowed to stay at the same park within 3 days of leaving after staying for your allowed amount of time. Also note: You're not allowed to stay at the same park for more than 40 nights in any 60 night time frame.
No camping as they are closed for maintenance possibly for the summer
Normal is 14 days but campground is closed.
Thanks for the info
