Guilford Lake State Park is located in the eastern part of Ohio and is considered one of the state's hidden gems. The park offers a variety of activities for visitors including hiking, fishing, boating, and camping. The lake itself is the main attraction as it spans over 400 acres and is home to a variety of fish species.

Some of the park's highlights include the spacious campground, which offers both electric and non-electric sites, as well as a group camping area. There are also several picnic areas and a beach for swimming and sunbathing.

One of the most popular activities at Guilford Lake State Park is fishing. The lake is stocked with largemouth bass, bluegill, crappie, and channel catfish. Visitors can also rent a boat or bring their own to explore the lake's many coves and inlets.

In addition to outdoor activities, the park also has a number of historical sites to explore. The nearby village of Hanoverton is home to several historic buildings, including the Spread Eagle Tavern and Museum and the Hanoverton Canal Town District.

The best time to visit Guilford Lake State Park is during the summer months when the weather is warm and the lake is best for swimming and boating. However, the park is open year-round and offers hiking and cross-country skiing trails for visitors to enjoy during the winter months.
