Our new facility provides patrons with a unique recreational experience. The Three Oaks Recreation Area is a reclaimed quarry that has pristine waters and excellent fishing. Patrons are able to rent rowboats, canoes, kayaks, sailboats, and paddleboats from a rental marina. A grass picnic area and various overlooks provide patrons with breathtaking views of the water and lake islands. In addition, the facility offers hiking trails, a playground/spray park, and a concessions area and patio.
