Twenty-Five Mile Creek State Park sits on Lake Chelan's south shore at 1,148 feet elevation, offering 79 sites and one of the area's most protected boat launches. The park has its own marina with fuel and slips, a small on-site store selling ice, firewood, and basic supplies, and a shallow swim beach that works well for kids. Cell service is nonexistent in the park itself, returning about two miles out.
Reviews indicate a mix of tent and RV camping with sites that range from grassy/treed to silt/dirt upper-campground sites; there are RV hookups and marina/boat-access sites.
Weather and SeasonsSummer brings the best conditions: mid-80s to low-90s during the day, cooling to the 50s and 60s at night. The launch and beach are fully active, making it prime time for boating and swimming. Expect strong evening valley winds, often 10 to 25 mph, that can tear up tents near the water and require careful boat securing. Summer weekends get crowded. Plan reservations early and stake tents well if you're near the shoreline.
Natural Features and SceneryThe campground spreads along Lake Chelan where Twenty-Five Mile Creek flows into the lake, with views stretching toward distant ridges. A sandy beach and fishing pier line the shoreline. The marina's wave wall creates a calm harbor even when afternoon winds churn the main lake. Grassy picnic areas offer shade, though upper sites sit in dustier, silt-based terrain. Wild blackberries ripen along the edges in late summer.
