The park is 5,000 acres where visitors can explore miles of hiking in a valley surrounded by oak trees and hosting a lake five miles long. Lake Del Valle is stocked regularly with trout and catfish. There are also large and small mouth bass, striped bass, and panfish. The public may rent motorboats, patio boats, peddle boats, canoes, and kayaks at the marina area. Any size boat may be launched at the public boat ramp.
