First section of the rail trail, 3 miles, is unpaved. Next 3 miles is paved and there are plans to continue the trail to the Monroe Town line but there is a missing bridge which is barring the way at the moment.
Good place to ride with the kids.
Take Route 25 (North) to Rte 127, White Plains Road. Head North towards the center of town. Past the light at the intersection of Daniels Farm Road, take first right onto Taits Mill Rd and look for parking on this street. Trail head is a few hundred yards up the road.
