What to expect on Chatham Rail Trail Extension loop from The Twinefield

The route begins on the smooth asphalt of the Old Colony Rail Trail, part of the larger Cape Cod Rail Trail system, guiding you through quiet residential streets and past serene pitch pine and oak forests. A unique highlight is running alongside the Chatham Municipal Airport, where you might catch small aircraft taking off or landing.
