Fall, usually late October through the first two weeks of November, is a particularly scenic time at Martin Creek. Visitors can marvel at the colorful foliage displayed by the many varieties of hardwoods interspersed with loblolly and short-leaf pine trees.
The park's forest shelters abundant wildlife, including gophers, swamp rabbits, nutria, white-tailed deer, raccoons, armadillos and squirrels. Park visitors enjoy excellent year-round fishing, due to water warmed by the power plant. Fish include largemouth bass, crappie, channel catfish, perch, ball and sunfish. Among the most commonly seen birds are mallard ducks, great blue herons, green-backed herons, great egrets, northern cardinals, blue jays, red-headed woodpeckers, bobwhites and northern mockingbirds.
