The State of Missouri accepted the Stonyridge property in 1974, and entrusted the operation of the property to the Department of Natural Resources, Division of State Parks. Bothwell State Park development called for construction of ball fields, tennis courts, and a swimming beach. With the departure of the Pettis County Historical Society at the Lodge, site staff took up the operation of the tours. Tours were now to be offered on a year-round basis. Reflecting this new focus on interpretation of the historic features of the site, the Division of State Parks redesignated Bothwell State Park as Bothwell Lodge State Historic Site in November 1992.
Visitors can now use the picnic area and hiking trail on a daily basis.
Tours of the Lodge are offered daily for a nominal fee. Group Tours are offered, with prior contact of the site staff. Acquired by the Missouri Department of Natural Resources in 1974, Bothwell Lodge is now one of 77 State Parks and Historic Sites. The Lodge is open daily for tours, a fee is charged.
