I had a great time joggling along the Croton Aqueduct trail to Lyndhurst. It was perfect joggling weather. This trail follows the path of a now defunct aqueduct that once provided water to New York City. It zigzags through much of western Westchester county, through several historic villages. Some stretches of it are densely wooded, and many houses along the trail are quite grand and architecturally significant. In some spots, you can get spectacular views of the Hudson. It is often crowded with lots of runners, cyclists, walkers and bird-watchers in calm weather. You may encounter deer along some parts of the trail.
Luckily, hurricane Sandy didn’t destroy a lot trees along the trail. The trail mostly runs on top of the old aqueduct, and so you can almost never see it. You can even go under the aqueduct it in a few places, but be careful. 
It’s large alright, but it’s not Downtown Abbey(Highclere Castle)
It runs through Tarrytown and Sleepy Hollow, villages made famous by Washington Irving’s novels(it also runs through Dobbs Ferry, Hastings-On-Hudson and Yonkers). The Lyndhurst castle is the most important historical mansion along the trail.
