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.

Great walk. But the section north of Woodhaven station is a dead end. I had to go back and walk city streets for a long section. All in all great walk from Soundview ferry station in the Bronx to Bronxville train station. I will return fir the next section

Great trail. Southern section paving is beautiful. Trail is clean with surprisingly little litter or debris. Some sections in southern Westchester seem like they laid pavement directly on top of the old rail road ties, but newer sections are very smooth. Safe for family rides with minimal road crossings. Mostly flat or shallow grade (up to 100’ per mile). Beautiful scenery through parks. Too bad that this route does not continue South through Van Cortlandt Park and connect into the bike networks of Manhattan. (About 2 miles away.) Some sections are very near the Saw Mill Parkway and Major Deegan. Parts of the Saw Mill / Bronx River still need cleanup. And access points in southern Westchester to the towns are not great. (Be prepared to street ride if you want refreshements.)

I did the southern part of the trail from Massapequa park to Bethpage park. While the scenery and lakes are nice, the trail needs repair. There are many cracks and bumps especially near the beginning of trail. Also there are several road crossings but cars were careful to yield to cyclists.

This trail is great for biking but there are a lot of people who use it for walking.

A nice 23 mile up and back from soundview. The most scenic part being from bronxville north to the dam. Definitely have a map handy though, as you will need to do street riding a few times. There are some hilly portions that will get you into gear changing which is nice. Bronxville has a great downtown with food options if you need to stop for a break. If this trail is ever connected it would be 5 stars for me. Solid ride and the dam at the conclusion is quite impressive.

It is perfect for quick morning ride with nice view.

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.

Level easy trail quiet and very pretty. Tricky entrance and exit onto busy road. Short easy trail. Wear boots muddy areas.
