The Air Line State Park Trail is an abandoned railroad line that runs through rural central Connecticut. Approximately eleven miles have been resurfaced with stone dust and bridges; parking lots are near completion. Another ten miles are scheduled to be completed and are presently under construction.

The trail passes through forests, rock-cuts, meadows, and borders wetlands and marsh areas. Several rivers and streams are crossed with two viaducts that provide wonderful views of the area.

Beautiful walk by meadows and water

Hiked March 16-17, 2024. This is a lovely, wide, multi-use rail trail of crushed gravel with no hard pavement, so it’s easy on the feet and knees. The trail runs past meadows, ponds, and marshes. Beautiful scenery. Signs here and there inform you of the railroad history. Saw a ton of happy and friendly locals walking, jogging, and biking. Truly an enjoyable and relaxed way to traverse a bunch of miles. Trish Ellis (aka Janie Walker)

Great in all seasons!

Wonderful multi-use trail. Perfect for family outings all year. A bonus are the historical aspects of this former railroad. Bring your camera!
