It is perfect for quick morning ride with nice view.

We started at Tait road entrance around 4:30 pm. Path was leafy but dry and good with great views.

The southern half of the trail is great - smooth, not too steep, and mostly shaded. The northern half, until you reach the North County Trail, is terrible. Cracked, potholes, and sunken spots that are hard to see for almost the entirety of the trail.

I am an experienced cyclist who doesn't mind hills and other challenges. My wife is a casual rider who likes mostly flat, but not boringly flat, rides.

I drove almost an hour to scout out this trail for one of the leisurely rides we like to do together. After literally two minutes, I turned around and rode back to my car.

This trail is NOT suitable for occasional cyclists, beginners, older riders, or younger riders. In fact, I don't really know WHO it is good for, as for someone like me who can live with a few hills, it is way too short.

Perhaps if it, at least, led somewhere scenic or lined with coffee and pie shops, it might be worth the effort. However, it appears to start in the middle of nowhere and end in the middle of nowhere.

I gave it two stars instead of one on the chance that it might get better after the first thousand feet I covered. You'll have to find out for yourself. I'm not going back.

We rode from Sleepy Hollow High School to the Croton Dam and back on 9 26 20, total 22 miles round trip.

This is quite a varied trail experience. First, there are several on-road segments that connect the trail sections. The trail itself was mostly hard packed dirt, with some gravel...you need a trail bike or a mountain bike. Basically flat, but some of the road crossings had ups and downs and there were a few slightly hilly areas too.
It’s a complicated route, you definitely need a map or a Ride With GPS route or something similar….trail has signs but not always marked clearly. Old Croton Aqueduct.org has a lot of info.
The first section, from Sleepy Hollow High School to Scarborough was all off road. Once in Scarborough, we took a detour down River Road, to Creighton, to Scarborough Station Road to avoid a section right along Route 9. Crossing Route 9 at Scarborough Road, you ride on-road up a small hill to Long Hill Street, where you pick the trail up again. This section ends in the parking lot of an apartment building You’ll need to cross Route 9 and make your way diagonally through Nelson Park and Nelson Sitting Park to Spring Street in Ossining. After a couple of blocks we took a right on Maple Street and then on the left you’ll see the trail proceed between buildings…sort of like a walkway. This “walkway” continues through Ossining, over a nice high bridge and eventually ends up out by the Northside fire house, where you pick up the trail again. The next big cue will be crossing Route 9 again at Audubon Street, you ride on road up to Piping Rock, take a left, and pick up the trail shortly on the right, finally coming out on Ogden drive. Turn left, ride on road to Old Albany Post Road, turn right, pass under the highway, and then you have the choice of turning right on Shady Lane Farm Road and picking up the trail to go around the GE property (this was very rough, hilly, and difficult) or staying on road, riding uphill and turning right on Hillcrest Road. Both options take you out to Indian Brook Service Road, where you’ll again pick up the trail and follow it to the Croton Dam, passing over Quaker Ridge Street a number of times.
The area through Rockefeller Park and Scarborough is really nice, including that off road detour in Scarborough where you can see the river behind some nice houses. The section next to Rockefeller park is really beautiful, you can see the hiking trails of the park from the Aqueduct. And the section immediately before you reach the dam is nice too, pretty wide, nice tree-lined stretch. I have to say though that the section to get to that (around the GE offices) is rough. And you have to ride through downtown Ossining, not hard but not of course a real trail, and there’s one section where you have to walk your bike up and over some steps. So, all in all – sort of a mixed review, some really nice sections and views but be aware that there are some challenging sections and on road sections too. And please note that there’s a whole other section south of here that goes all the way to NYC.

Great trail with greens and manageable hills. But some dangerous crossings and noise highways. Recommend ear buds. I wouldn’t take my kids for whole trail. Just south is fine. Will definitely go during foliage season.

I've logged about 20k miles of road biking across the United States namely in WA, MO, OH, PA, MD and FL, and maybe 10% of that on trails. To get to stay 99% of the time on a car-free trail for almost 50 miles (as a loop) is rare- and to have some scenery- is nearly unheard of. Thrilled to be in CT now and using this as my go-to ride.

We rode this trail on 9/12/20, starting at the parking lot on route 63.
Overall, a nice trail, but it has a lot of plusses but also some things that could be considered “minuses” by some.
Plus:
Shaded, pretty sections high over the adjoining forest.
Some nice scenery including horse farms (and horses share the trail, we passed several), plus several ponds. Route goes through the woods the whole way…very little in the way of passes through suburbia.
Not crowded.
Not a huge number of road crossings, and typically with good sight lines.
No big hills, some gradual ups and downs.
Minuses:
Most of the train is hard packed dirt or stone dust that makes for a good surface. However, there are significant sections that are a bit rougher. Some of the road crossings involve a downhill, cross the road, and then an uphill…often with a lot of stone or sand involved. There is a section around mile 8-9(when going West) where the trail follows something like a creek bed, with large stones that make it problematic (we walked this section). There are some embedded stones along the way so you have to watch where you’re going and steer around them..or even walk briefly. Some sections do have some drainage issues, so just need to be careful there. And parts of the trail become more like singletrack. We were able to navigate the entire route with our mountain/trail bikes (30 or 32 cc tires)…I would not recommend a conventional skinny tire road bike here.
Please don’t think the minuses outnumber the plusses here. Overall I recommend this trail because it’s pretty and ridable. Maps are available at the Connecticut DEP website.
Finally I recommend starting at the Naugatuck route 63 parking area…several other posters have noted that there’s basically no parking if you start in Southbury.
Check out the Air Line trail and the Hop River trail, not too far away in central Connecticut, for other options you may want to try.

Took the family and it was very clean and an excellent time. Windy and lots of hills and downhill runs. Recommended
