If you're living in or visiting Hudson, this is the most easily accessible trail system you'll find. This only says there are about 2 miles of trails but there is actually a lot of more if you do all the trails. I've hit just about every inch of trail and I'd say there's closer to 8 miles if you include the Stockport Greenport trail which takes you to Harrier Hill Park. None of them are strenuous but at certain points you get good views of the Catskills. Great for a mellow post-work hike (like I have done many times) or if you're not feeling up for an adventure further outside of town.
