What loops are the first come first serve? I've tried calling the number several times but there's no answer so I want to make sure I know what's available.

It's the first and last one. The two middle loops are reserve only.

I believe all four are

Hemlock is for sure.

I'm not sure about the campground. We camp off road for free. I would keep calling or try the parks department for Mason county

I believe it is Violet (I think) and Hemlock (for sure)

Thank you! Are things pretty full already this year if I came on a Sunday-Thursday?
