Casawinati Campground is a family-owned and operated campground situated along the Mississippi River just below the Playfairville Rapids in Lanark, Ontario.

The river setting is well suited for swimming, fishing, canoeing, and kayaking, and wildlife is particularly active through the summer months. The campground offers 25 full-service sites, 46 water and electricity sites, and group tent areas without service.

Sites are spacious and heavily treed for shade. Facilities include a playground, a large community shelter, clean washrooms, a beach area, and a shaded gazebo with Adirondack chairs overlooking the river. The Blue Heron Golf Club is located nearby.
