Twenty-Five Mile Creek
Boaters and campers, come on down!
Twenty-Five Mile Creek State Park offers one of the top boat launch and moorage sites on spectacular Lake Chelan.
This small state park has a modern marina located nearly halfway along the 50.5-mile lake. Use the park as your launch site to get on the water and set out for distant shores.
Discover Lake Chelan's deep blue waters and its small shorefront communities before dropping anchor in a secluded turquoise cove or returning to the park, where a little store with a deck offers amenities and colorful sunsets.
Planning a getaway on terra firma? Bring your RV or pitch your tent in one of the creek-side campsites that dot the forested park. The area is home to spectacular summer hiking and mountain biking, and the park makes an excellent base camp for such day hikes as Pot Peak, Stormy Mountain and Devil's Backbone in the North Cascades.
Twenty-Five Mile Creek State Park is a 232-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.
The marina affords visitors excellent boating access to the upper reaches of Lake Chelan.
