Kirby Lake Boat Ramp is a public access point located at Kirby Lake Primitive in the Town of Maple Plain, 6 miles north of Cumberland, offering a primitive boat launch managed by the Wisconsin Department of Natural Resources.

The ramp provides access to a 98-acre lake with a maximum depth of 19 feet, and is situated adjacent to a Barron County-owned primitive campground with walk-in tent sites, picnic tables, and fire rings available on a first-come, first-served basis.

This location serves as a gateway for boating and fishing activities on Kirby Lake, a mesotrophic lake known for its clear water and diverse aquatic plant community.
