Beautiful trail, easy bike ride. Went on it on a Sunday, and there wasn’t too much foot traffic. Going through it this time of year felt magical because of the foliage.

Beautiful trail. I had a great morning here for a 2h walk with family and friends. Looks great for biking as well.We saw a few frogs along the way, plenty of fun for the kids.

The ambitious New York, New Haven and Hartford Railroad got its name, Air Line, from the soaring viaducts built to ensure a level trackbed on its high-speed route from New York to Boston.The Air Line opened in 1873 and the section between East Hampton and the Connecticut-Massachusetts linehad been abandoned by the mid-20th century to become a trail.The 25-mile southern portion of this route, from East Hampton to Windham, is designated a National Recreation Trail and is a breeze to walk or cycle on.The Air Line State Park Trail has a smooth stone dust surface and crosses buried 19th-century trestles at the Rapallo and Lyman viaducts, with benches positioned at scenic spots along the route.

The section I have visited a couple of times is great. There are spots with some good views and areas that have some unique and pretty terrain.

Easy walking trails. Very nice place to visit

Gorgeous trail. Very safe, you will cross paths with families and all ages walking, running or biking this path. Highly recommend.

Great place for a bike ride, or even a walk! Nice views, flat terrain, so not too much of a workout, aside from length. Its a nice spot.

Great bicycling trail. A bit bumpy inn places. Adventurous.

The bike trail was amazing my wife and I had a wonderful weekend out there.

Great place to ride a bike or go for a n8ce level walk.

We are so excited about finding this place to ride our electric bikes. Shade, level, smooth trails mostly.

A great place to bike and run. Mostly flat, but really fun to run on.

Great trail for bike riding with kids. Just perfect!

Great bike trail. Hard packed gravel and beautiful scenery

Beautiful trail great for long training runs. Only a couple of spots where it is broken up and requires some road navigation. Very quiet and peaceful.

One part is a nice place where you can walk to the center of the town

Terrific for gravel grinding...alone! Beautiful nature. Feels super safe. Enjoy!

Well maintained!

Great biking trail for beginners, looking for a ride to test your endurance this is it. Not hard.

It was a very good trail for children due to its flatness

Beautiful trail, nice flat surface with wide walking or biking bath.

Some beautiful segments of trail, well maintained, super busy on weekends

I grew up along this path, and Ive travelled it many times. Its very flat since it used to be railroad tracks, and the views along it are fantastic. The farther you go the more beautiful it gets! Great for little kids and dogs, and super bike friendly.

Amazing, wide, clean trail. Many options

Not so nice.with all the horse flies and mosquitoes. posted July 5 2020.

Awesome trails!! Accidentally biked 11 miles

My friend likes it.

Great trail for mountain biking, nice scenery.

Absolutely beautiful trail. Lots of variation in scenery throughout, and it has a consistently flat trail. The history of the trail is neat, and most areas are very wide, giving plenty of room for bikers and walkers.

Beautiful, scenic trail for biking, jogging, or walking. Not ideal for road bikes as its not paved.

Beautiful well kept trail

Its is a beautiful trail my wife loves it she bike rides 6 miles of it every weekend when we are in town

This is an amazing trail for biking with kids

Heard a frog and watched its back legs dive down

Shaded and well kept trail...safe too...good for walking, running, biking...lots of families present as well...occasional horses

Wonderful place to walk a dog, ride a horse or bike or just hike. Meet good people. Trail extends eventually yo the MA border and much of it is rideable or walkable.

Improvements to trail are underway but the other rail is still passable and well maintained.

WHAT A FUN INTERESTING WALK ON A WELL MAINTAINED CINDER PATH. LOTS OF BIRDS, SAW A GREAT BLUE HERON, HEARD A PLIEATED WOOD PECKER (COULDNT FIND HIM, BUT HE WAS CLOSE BY). SAW PEOPLE ON BIKES, WALKING DOGS. MOMS PULLING WAGONS FULL OF KIDS. A GREAT WAY TO SPEND A SUNNY DAY. PLENTY OF FREE PARKING RIGHT NEXT TO A POND THAT USED TO BE AN OLD CRANBERRY BOG. MET MANY INTERESTING PEOPLE.

Great rails-to-trails trail. We biked, starting at West Hampton, and rode to Colchester and back. Had lunch at Harrys in Colchester. Nice day!

Great place to ride the bike and walk the dog

Nice flat. Good for cycling and walking. Nice views.

Beautiful, well groomed, you gotta give it a try from the cranberry bog (3 miles to next parking lot).

Great walking hiking dog walks just clean up after your furry friends

Great bike trail

Great place to walk with your family would recommend coming.

If you live nearby, plan on walking/running the entire airline. Easy access at many places along the trail. Very flat and mostly well maintained.

Gorgeous road. Beautiful butterflies follow you.

Beautiful trail, good spot to collect your thoughts.

Beautiful trail

Best outdoor experience, sometimes wish signage was better

Its a good place for a walk or bike ride. Wide enough to accommodate both kinds of traffic. Maintained well enough so that mud, etc. is not an issue. Hoping to find some loop trails that are similar.

Such a cool rail trail. I need to do more than just a couple of miles and explore more of this trail.

Nice place to go for a hike, run or bike ride. First time at Colchester section of airline trail.

Great place for a bike ride

Gewat place to go for a walk or biking

Very good for walking

*** UPDATE 2019 - Portland section is NOT SAFE due to abutting residential property target shooting with 50 yards of the trail. **This trail has been there for longer than anyone reading this. ATVs and dirt bikes kept it single-track for decades and it was hike-able/run-able. The latest improvements from Cobalt west into Portland are wonderful, its about a 4 mile loop if you go from one end to the other.This has been a wonderful example of making the history and woods of the area accessible to everyone. Its great to be out there in any season.Only 1-1.5 miles separates the Cobalt -end from connecting to the Westernmost-end in East Hampton at Aldens Crossing, hopefully this gets done with soon!EDIT- The Portland leg of the Airline Trail will be connected to the East Hampton end by the end of 2018. Construction about to begin now (August 2018).Also- THANK YOU to the majority of folks to keep your dogs on leashes. While yours may be a creampuff, other dogs are not so friendly and some people are afraid of dogs, in general. Thank you for being considerate.Also also- This should be totally apparent by the NO MOTOR VEHICLE signs, but dirt bikes, even at slow speeds, no longer have a place on the Airline Trail. This isnt because we dont love you, its because many peoples kids and dogs are afraid of them. The vast majority of dirt bike/ATV riders have respected this (and were always respectful to passing people slowly before the overhaul when it was just a singletrack foot path), however some are still insistent that this doesnt apply to them. Please, just dont ride on the trail anymore, thank you.Also also also- I get asked a lot about parking. You can park at the westmost-end off Middle Haddam Road (now marked on Google Maps) and also there is space at the crossing of Pennfield Hill Rd and Depot Hill road in Cobalt.Finally- Portland residents, please slow down for people who look like they are intending to cross in the clearly marked crosswalks at Breezy Corners, Pennfield Hill, and Depot Hill Road. I know its new and youre late for something, but theres a lot of small kids on bikes crossing these roads and Ive seen some very close calls already.

Always well maintained. Breaks off to great riding trails.

What a great trail. Miles of riding with nice scenery

Wonderful path that stretches for miles. Crosses over riders, passes by ponds, would recommend riding a bike!

Very nice place to run.

Awesome sights to see as well as a simple flat walk that goes for miles. Great for bikers, walkers, joggers and dog walkers!

Best bike or hike trail in the state for a relaxing day in the outdoors. Compacted gravel very well maintained. Trail runs for 20 miles starting in East Hampton Smith Rd. Ending at the Willimantic train museum. It picks up again at the Northeast side of Willimantic.

Awesome place to bike or hike. Very neat scenery

Very peaceful and beautiful

Terrific Greenway for a stroll with the dogs.

Nice place to ride with no cars to worry about hitting you.

People need to learn - you bring it in, you take it out!! No garbage bins!!

This is a great hike and biking trail.
