The park covers 639.8 acres of land on the northern shore Lake Bob Sandlin about 10 miles southwest of Mount Pleasant.

Lake Bob Sandlin is named after Bob Sandlin, a major proponent of the lake, who was a local businessman, civic leader, and president of Titus County Fresh Water Supply District No.

[5] The park offers over three miles of hiking and biking trails, a fishing pier and boat ramp, and opportunities for swimming, picnicking, geocaching, kayaking, and other outdoor activities.

It also features campgrounds with recreational vehicle hookups, covered shelters, and primitive cabins and tent sites for overnight stays.

The park is located at the intersection of the Piney Woods and Blackland Prairie ecoregions, and thus has a diverse variety of wildlife including white-tailed deer, raccoons, coyotes, gray foxes, fox squirrel, and bobcats.
