Seasonal upper Lake Chelan campground with 36 numbered sites, including seven full-hookup and four partial-hookup sites, plus showers and a 30-foot utility limit.
Twenty-Five Mile Creek State Park is a seasonal campground and marina on Lake Chelan. The current official map numbers 36 campsites: seven full-hookup sites, four partial-hookup sites, and 25 standard sites. Utility sites have a published 30-foot maximum. Washington State Parks lists showers, seasonal groceries and boat fuel, and a trailer dump on the current map. The boat launch has a later, lake-level-dependent spring opening than the campground.
The park lies at the road-accessible upper end of Lake Chelan's south shore. Nearby mountain trails and lake access are affected by wildfire, weather, road conditions, and seasonal water levels.
Practical guidance assembled from current operator maps, park pages, and clearly identified community observations.
The 36-site total includes seven full-hookup, four partial-hookup, and 25 standard sites. Utility sites are limited to 30 feet; verify the selected pad and launch status.
