Fillmore Glen State Park is an oasis of cool, dense woods crowding into a long, narrow gorge. Its hiking trails offer spectacular views, unique geological formations, including five waterfalls, and a botanically rich glen. The park has 60 campsites, a stream-fed swimming pool and fishing in the Owasco Lake inlet. In the winter, hiking, cross-country skiing and snowmobiling are permitted on unplowed roads.

For those who prefer the luxuries of home, the park offers a full service cottage located on the shore of Cayuga Lake at Long Point. Cottage amenities include a kitchen with a gas stove, refrigerator, sink, full bath, hot water; electricity, bedroom with double bed and dressers, main room with a sleeper sofa, furniture, dining table with chairs, a wood stove, boat dock, picnic table, fire ring and grill and a small lawn area.
