Keller Park State Recreation Area, located northeast of Ainsworth on Bone Creek, provides boat ramp access for non-powered watercraft and electric motors in a scenic setting nestled among tree-covered bluffs.

The 196-acre area features five fishing ponds with a footbridge across the creek, primitive restrooms, picnic tables, and shelters, making it an accessible spot for paddlers and anglers seeking a quieter recreational experience away from larger reservoirs.
