Watkins Glen State Park - We highly recommend hiking the Gorge Trail here!
Geneva Lakefront Trail - Parking here also brings you to the Finger Lakes Welcome Center.
Seneca Mills Falls - Parking on Outlet Rd makes for a short hike to the falls.
Shequaga Falls - Right alongside the main road, easy for a quick stop.
