Things To Do



Old Furnace State Park contains a three-mile hiking trail that starts in the parking lot and leads you to the top of the cliffs overlooking Half Hill Pond and down to the parking lot and boat ramp at the northern end of Ross Pond. The trail continues along the western edge of Ross Pond to Squaw Rock Road. The views from the top of the cliffs are stunning. The cliffs tower 200 feet over Half Hill Pond and give you an uninterrupted view over the eastern half of the town of Killingly and into Rhode Island.
