Twenty-Five Mile Creek State Park

About
Twenty-Five Mile Creek State Park is a 235-acre inland waters camping park on the forested south shore of Lake Chelan. The park separates the mountains from the lake and is surrounded by extraordinary scenery. This park has a modern marina nearly halfway along the 50.5-mile lake.
Is Twenty-Five Mile Creek State Park fully booked?
A campground showing no availability is almost never full for good. People cancel — plans change, weather turns, someone books three weekends and keeps one — and the site goes straight back into the booking system, usually without warning and often at odd hours. The reason sold-out campgrounds feel impossible is not that sites never free up; it is that nobody is watching at the moment they do.
