Rode this on a Summer day Parked by Quassy Amusement park and rode to Maggy My Fly's (a parking lot close to Maggy's, they do not allow parking). It was a mostly downhill ride on paved trail. Along the way there is plenty of green space and lots or roadway, there are a few short totally wooded sections but plan on looking at road for the bulk of your ride. Plenty of places to get food and drink along the way, and even a couple of public parks. This one was likely a one and done for me.

We were looking for a ride that provided a good workout, beautiful foliage and a break from the city. The path was straight, flat and paved - so great for all level riders and all age people. The town of Goshen is great. The trail ends (or sort of starts there) depends which side of it you want to start on. There is a portion beyond Goshen in Middletown. To get to that piece - you need to go through the town of Goshen using W. Main Street. You must stop at Sweet Tymes for a treat. Continue to proceed down W Main Street for about 1/4 of mile and on the right you will see the start of the bike path again. You know you have gone too far if you get to the cemetery on the left side of W Main Street. I would also stop in Chester ( you will see the old converted train station) and grab a bite at the Rustic Wheelhouse. Promise it will be a perfect day!

Updating my July 2020 review, the road down to the Nyack Beach State Park has reopened.
And at the top of the newly reconstructed road to the right of the entrance fee kiosk is a newly constructed foot trail that will take you to the Long Path with access to the Hook Mountain summit with great river views.

Parksville Rail Trail is one of our favorites! It’s gorgeous year round (though usually quite wet in parts, and icy in winter) but it’s one of our go to trails for a quick hike. Great for kids too!

Beautiful and well maintained…feels like it was built last night! Maybe could use a few benches but the real issue is the dangerous berms at the intersections mentioned by a previous reviewer. Truly horrible design! We saw a rider hit one hard. Fortunately he didn’t fall. They should be removed but in the meantime the curbs should be painted and potted plants placed on them to increase visibility. You will enjoy this trail just be safe.

I did this trail end-to-end yesterday as an out-and back from the southern end (no official parking at the trailhead but two supermarkets nearby could be utilized).
Overall in good to very good shape.
The non paved sections are OK for all type bikes except perhaps not for road bikes if the trail is wet.
The on-road sections are generally well marked by Empire State Trail (of which this trail is a part) signage.
Informative signage along the way.
It's not exactly a flat ride. My cycling app had it at over 1800 feet of elevation gain for the out-and-back.
Tip: About 6 miles from the southern end is the Hudson River Skywalk over the Rip Van Winkle Bridge with great views of the Hudson River and the Catskills.

We started the trail in Middleport parking on Palmer Ave. Highly recommend this direction as it’s mainly uphill to Harriman. We clocked 19 miles exactly to Harriman. The uphill is not super intense but is uphill so the way back was super fun and easy! We stopped in Monroe on the way back to Middleport. 38 miles in total ALL PAVED and 99.5 % trail. Excellent. Little weird spot right before Goshen as the trail ends abruptly with no signs. Head into the main town of Goshen and turn right at the wine store and you’ll be back on track!

We biked the newly completed Under Mountain Road to Millerton. We have biked the other completed sections in the past and this newly completed section does not disappoint . Very scenic and easy ride with our hybrid bikes.

Well Maintained trail as we biked the central to western end. We would have biked the eastren side but it was closed for a maintenance reason. Turned out all the better as most of the scenic overlooks were on side we biked. Our hybrid bikes handled the packed stone trail very well. Would certainly return again
