Located in northeast Alabama on the Tennessee River just east of the town of Guntersville, in Marshall County, Lake Guntersville Resort State Park sits on 6,000 acres of rolling hills overlooking Lake Guntersville. Hiking, picnicking, swimming, and camping are among the many recreational opportunities available to visitors. The state park opened in 1974 and was the premier park in the system at the time. On April 27, 2011, a tornado struck the park, damaging or destroying many of the facilities. After several years of renovation, the park and its facilities were again fully functional. The park has been inducted into the TripAdvisor Hall of Fame for winning its Certificate of Excellence five years in a row.

The park's Nature Center offers a series of nature programs throughout the year that include guided nature hikes, campfire talks on various subjects, and a conservation celebration and also has displays of local flora and fauna. Each Saturday morning, a park naturalist leads guided nature hikes that follow moderate trails and take approximately two hours. Visitors are likely to see deer, waterfowl, and eagles and their nests. The park has become well known for its Eagle Awareness weekends, held annually in January and February. Naturalists, speakers, nature programs, guided hikes, and tours focus on the lake's resident bald eagle population.

The park's 38 miles of hiking trails range from short, easy paths to lengthy, difficult trails with extreme elevation changes and rocky hiking conditions. The many trails offer access to the park's natural attractions, including hidden waterfalls, rocky ridges, grand views of Lake Guntersville, caves, and old home sites. Trails range in length from a ½-mile to 3½ miles and form a network that allows hikers to traverse the park in a number of configurations. A 16-mile-long horse trail traverses the park's mountainous terrain and winds up and down steep ridges and valleys. It passes by the remains of old home sites and the ruins of a grist mill.
