Summer Hill State Forest encompasses 4,355 acres of dense forest land and is located in the towns of Locke, Sempronius and Summer Hill in southern Cayuga County. Some of the more popular recreational activities include hunting, trapping, wildlife viewing, snowmobiling and horseback riding. Horseback riding has grown in popularity within the forest, and an informal trail system is currently in existence. However, since this area can become very wet at times, the season of use is limited to May through October, and the DEC respectfully requests the use of sound judgment and good sense when contemplating a trip to the trails.
There is a 28-mile snowmobile trail that runs through Summer Hill State Forest, partly on seasonal town roads and partly in the forest. At this time there are no plans to construct other formal facilities, and management will continue according to the Hewitt-Cayuga Highlands Unit Management Plan
