If you mean the one in WA State around the Wenatchee area, I've got my first booking there next year. I'll be in site 21, which is a pull thru on the lake side.
We went thru the park earlier this year when we were at Wenatchee Confluence and it seems to be a 'hidden gem', but you will need to make reservations at least 9 months ahead of time... To the DAY at 7am inthe morning.. You might even have to go a few days ahead of time! To even to get a choice site..
Good luck!
