Air Line State Park Trail

Trail Map

Description Suggest an Edit

Air Line State Park Trail winds for 53 miles from the northeast corner of Connecticut, where the state borders Massachusetts, down to East Hampton in the heart of the state. Over the state border, you can make a contiguous connection to the Southern New England Trunk Line Trail, a scenic 22-mile adventure that heads east to Franklin.

The gravel pathway is nearly seamless with only two short gaps: one in Putnam and the other in Willimantic. A 3.4-mile spur off the main route links the trail to Colchester. Though a tad rougher, the spur offers an enjoyable ride through hemlock woods.

The rail-trail showcases the engineering behind the Air Line Railroad, laid down through this hilly region in 1873 as a direct route between Boston and New York. As its name implies, the tracks ran flat and straight, like ‘a line in the air.’ The Air Line employed the finest trains of the day, featuring the Pullman Palace Car, marketed as the White Train for its luxurious white-and-gold decor.

About three miles from the southern end of the trail, you'll cross the Rapallo and Lyman viaducts. Built in the 1870s, each spans more than 1,000 feet, the latter soaring more than 150 feet above the valley floor. In 1913, crews reinforced the viaducts with rock and sediment to support heavier trains. Visible from trailside benches, the top corner of each span pokes out through the fill.

Just a half-mile from East Hampton, you’ll also find a few small waterfalls, created when railroad crews blasted Bishops Cut through solid rock.

The trail, between its junction with the Hop Brook State Park Trail just north of Willimantic and its junction with the Putnam River Trail at Putnam, is part of a massive trail network known as the East Coast Greenway, which will connect communities along the Eastern seaboard from Maine to Florida.

Willimantic connection between north & south

Did a recon of the trail connection on 6/26/16. Found very nice paved trail north of Bridge Street to the junction with the Hop River Trail at the east end of the newly decked river bridge. Nice explanation panel at the bridge, but the site could use more

North Section, major improvements, nearly connected back together.

Recently rode the north section starting near Tuckie Rd in North Windham. I went a couple of years ago it and was quite rough, washed out, and poorly marked, but with the recent extension of the South section over the Wilimantic river, there have also more
