Harriman State Park has so many beautiful attributes: mountains, forests, caves, lakes, campsites, streams, and hiking trails galore. It covers a massive amount of land, and you could easily spend a week hiking and even camping here if you wanted to. The campsites are scenic, some even featuring some very cool lean-tos. There's a great variety of hiking options, from easy to very challenging, and multiple scenic vistas as well. The Pine Swamp Mountain hike was beautiful. Lots of little streams to cross which was fun but may require some agility and care. To be clear, you want to follow the green blazes, then walk right when you see the yellow blazes, then walk right when you see the white and red triangle blazes. It’s a wonderfully varied trail. Even though the distance is pretty short, the terrain is kind of uneven so you end up getting a decent calf workout. The Long Trail along the lake has green blazes, connecting to yellow blazes of Dunning (the wide trail), and then white with red triangles is the Arden-Surebridge. The trail is nice mix of scenery, valleys, small hills, view of lakes, and small stream crossings. The bugs were definitely around so I would recommend some bug spray. Harriman is actually less than an hour from NYC, so pay a visit if you get the chance. It's beautiful.
