This is not really a one long trail but a series of segmented trails. While the beginning of each segment is marked with an "OCA" post, at the end of most segments there is no indication about where to find the next thread of the trail. Often you have to go through busy suburban streets to make the connection, some of which are quite dangerous. Other reviews recommended using GPS on your phone, but Google maps only indicates where the various trail segments are and it is difficult to find out how they connect. My friend & I attempted to do the northern half of the trail from Tarrytown up to the Old Croton reservoir. When you get to the Clearview School in Scarborough, you have to ride on a very busy Rt. 9, which has no shoulder, until you can take up the trail on Scarborough Rd. When we got to Ossining, the trail ended with no indication how to continue, so we again had to ride on Rt. 9. Then my friend hit a broken drainage grate on the side of the street, which was covered with leaves so that she could not see the gap in the pavement. It threw her head-first onto the asphalt. She was knocked out for several minutes, had a concussion, was bleeding profusely and nearly broke her neck. I called an EMT which took her to a hospital, where she stayed for two days and had stitches to her face and several tests. She was lucky she was not paralyzed (thanks to wearing a helmet). Exercise GREAT caution if you take the Ossining part of the trail. Some of the other segments are O.K. but some of them are just like riding through peoples' backyards.

Phase 1- the makings of a wonderful trail! Anxiously waiting for the completion of phase 2.

I have been riding this trail for years. As of November, 2020, a wonderful new section has just been introduced, stretching from Millerton, NY to Under Mountain Road. This means that the trail now covers almost 24 miles one-way from Wassaic NY all the way to Orphan Farm Road near Copake. This is a classic, beautiful trail the runs through a valley, with so many nice sections: tunnels of trees looking out over farms, places to stop in Amenia and Millerton, a section that runs right to the entrance of Taconic State Park, several raised ridges with views of fields on both sides. The newest area, from Millerton to Under Mountain Road, is perhaps the nicest of all, as it runs through an area with views of the Taconic Berkshires and runs over multiple ponds via the old train bridges (now updated for bicycles). I’ve been on rail trails all over the northeast, this is one of the very best.

The Air Line State Park Trail is one of my favorite bike trails in Connecticut. Rode our bikes there last week and was very disappointed with the recently resurfaced section from the Cranberry Bog in East Hampton. The gravel that was used in the resurfacing is to soft and to deep. Has only been open for a week (10/28/2020) and it is already marred by craters from horses and foot traffic. The ride is bumpy like a wash board. At one point I swerved to miss a pile of horse droppings and got to close to the edge which then collapsed under my bike causing me to fall. What was once a favorite section of the trail for us, is now a major disappointment.

We parked by the pet store mentioned in a previous review and biked to just passed the covered bridge, maybe 6 miles out? Beginning of trail is rough but that ends quickly . Nice ride in the woods. Not much to see. It was a slight incline on the way out which made the return better. I wish there some benches along the way to take a break.

We did this in a Sunday afternoon and it was impossible to ride our bikes across. We walked most of the way and the views were great going over the bridge.

This trail is an easy ride for everyone. It’s well maintained with plenty of benches to rest and a mixture of sun and shady spots. The end of this trail leads right into the Walkway over the Hudson.

One of the best trails I have done. Nice and smooth. You must do Walkway over The Hudson.

My friend and I rode from Millwood on the North County Trail and just kept going. We ended up on the Putnam Trailway for a total of 46 miles. There are several decent hills on this segment of the trail. There are some street crossings but they are not very busy roads. You eventually come to the end of the trail, which is clearly marked. Near the end of the trail is a large reservoir. The trail is completely paved with just a few bumpy spots. We rode on 10/10 and the foliage has not changed much yet.
