Harriman State Park is the second largest state park in New York with 200 miles of hiking trails, over 30 lakes, and only an hour's drive from NYC. Check out www.myharriman.com to learn everything you need to know about this park. Below are my favorite hikes in Harriman State Park under 5 miles that you could do in 3 hours. I picked these hikes because they offer expansive panoramic views and easy access to lakes. Tom Jones Mountain is the only hike not accessible until April because road 106 leading to the trailhead is closed.
