In addition, Little Grassy Lake is located near the campground and provides plentiful bank fishing. The lake is owned by Crab Orchard Wildlife Refuge. A special federal sticker is needed to boat fish on the lake. The sticker is not available at Giant City State Park. Well-kept playgrounds, picnic areas, and shelters exist throughout the park.
Some shelters are available for reservation.
No reservations for camping are taken at Giant City. Picturesque hiking trails provide visitors with days of enjoyment. The Post Oak trail is handicap-accessible with a paved walkway and scenic overlooks with handrails so that all visitors can experience a dry blufftop forest community. A favorite attraction of the park is Giant City Stables , a complete horseback riding facility. The Stables are open from May 1 to November 1 each year.
