  • Boating

    The Pactola Reservoir Complex has two boat launches and a marina. There are boat rentals at some of the campgrounds.

  • Bicycling

    The Osprey Trail is a 2.2-mile trail that includes two loop trails and a spur trail to an overlook. The trail was appropriately named because osprey are often seen in the Pactola Lake area. Osprey, also known as fish hawks, are fish-eating specialists, with live fish accounting for about 99 percent of their diet. Osprey are spectacular divers. Once they have sighted their prey, they fold their wings tightly, descend swiftly, and enter the water feet first, often submerging completely. Long sharp talons and barbed pads grip the slippery fish.
