Crystal Lake Access offers a public boat ramp on the south side of the lake off 320th Street, with an additional access point on the northwest corner off Mallard Ave.

The hard surface ramp provides convenient access for both motorboats and paddlers to this 250-acre natural glacial lake, which features amenities including a fishing jetty, picnic areas, beach, playground, restrooms, and a fish cleaning station managed by the Hancock County Conservation Board.
