Air Line State Park Trail Description

Overview

The Air Line State Park Trail winds 60.3 miles from the northeast corner of Connecticut, where the state borders Massachusetts, down to East Hampton in the heart of the state. The pathway is nearly seamless, with only one major gap through Putnam.

Northern Section: East Thompson to Thompson

The northernmost section of trail feels completely secluded, as it has few entry points and no view of the roads or sound of traffic for miles.

A word of caution about the trail’s surface, however: The original ballast covers this 6-mile northern section, and it becomes bumpy and rocky at various points. Riders often have to dismount due to the uneven nature of the ballast, so a fat-tire bicycle is highly recommended. This portion of the trail reaches its southern end in the southern outskirts of Thompson, near the border of neighboring Putnam.

A gap of 7.5 miles lies between the northern and southern sections of the Air Line State Park Trail. Pick up the pathway again at the intersection of Averill Street and Railroad Street in Pomfret Center, a small village nestled within the larger Pomfret, one of the oldest towns in the state with its incorporation in 1713.

Southern Section: Pomfret Center to East Hampton

From Pomfret Center, the pathway continues for just over 19 miles southwest to Willimantic, skirting Mashamoquet Brook State Park, Natchaug State Forest, and Goodwin State Forest, which offer numerous recreational options such as hiking and equestrian trails, camping, and wildlife viewing.

Arriving in downtown Willimantic, the trail ends at Jillson Square Park, but with a short bit of on-road riding, but the trail picks back just south of the intersection of Bridge Street and Riverside Drive. Traveling west along the Willimantic River, the trail passes the Connecticut Eastern Railroad Museum in 0.8 mile. For history buffs, its vintage locomotives and railroad buildings are well worth a visit.

Heading southwest down the trail, the path arrives at a fork in Hebron after 8.3 miles. Keep right to stay on the main Air Line State Park Trail; the other option is a 3.5-mile spur to Colchester. Though the trail is primarily dirt here, this section offers many attractions that make it worthwhile. From the fork, it’s 1.4 miles to beautiful Grayville Falls Town Park, which offers waterfalls and wooded hikes. Nature abounds the trail continues along, and trail users have access to Raymond Brook Marsh and Salmon River State Forest.

Numerous bridges offer lovely views, including the Blackledge and Jere-my River crossings. When the trail reaches the Bull Hill Road trailhead parking, trail users can take an on-road side excursion of 1.4 miles to reach the Comstock Covered Bridge. Originally built in 1791, it’s one of the last remaining historical covered bridges in the state.

From the Bull Hill trailhead, there is only 3.6 miles until trail’s end, but there’s still more to see. The trail crosses the Rapallo and Lyman Viaducts, which were originally built in the 1870s and offer stunning views of the surrounding hills and forests. The trail ends in East Hampton, once known as Bell Town for the 30 bell-making companies that settled here.

The southwestern most section of the trail is often called the Portland Air Line State Trail, and it runs between Depot Hill Road near Old Middletown Road and dead ends in the woods near Jobs Pond. 

Connections

At the MA-CT state line (the trail's northeastern most endpoint), trail users may continue seamlessly along the Southern New England Trunkline Trail.

In Willimantic, the trail connects to the Hop River State Park Trail.

The Air Line State Park Trail is part of the developing East Coast Greenway, a 3,000-mile route Florida to Maine. 

Trail History

The rail-trail showcases the engineering behind the Air Line Railroad, laid down through this hilly region in 1873 as part of a direct route between Boston and New York. As the railroad’s 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.

Hard packed surface

We love biking the Airline and have used non electric hybrid bikes as well as e-bikes. Both work well. On 10/28/2023 we biked the section from Willimantic parking at the Connecticut Eastern Railroad Museum area and pedaled to Rt. 207 Lebanon Rd, Amston, CT. FYI, we're in our 60s and encountered no difficulties with the terrain.

Air line trail Pomfret to Willimantic.

Have been on this stretch of the Air Line trail numerous times over the past few months as I have had the good fortune to make it part of my daily work commute. Overall it has been fantastic and in good shape. There is a one mile stretch from Goodwin State Forest (Potter Road) to Roger's Road (on the Chaplin Line) that needs some work. It's a bit rocky and is a single lane for a bit, but it is passable - just be careful. Whatever direction you are headed you will be rewarded with some beautiful scenery and easier riding once you past this stretch. I love this part of the trail; the pond near Station Road (Hampton) and some of the overlooks in Chaplin are my favorites. Enjoy the ride.
