There are a lot of art installations scattered throughout the park. My favorite is the "Mirror Labyrinth" by Jeppe Hein, part of the "Please Touch The Art" exhibition funded by the Public Art Fund.
You'll find the new luminous "Understanding" sculpture by Martin Creed at Pier 6.
The floating dock at Pier 2 offers kayaking for free on the weekends. The only catch is you have to get there early enough to sign up.
There's also Jane's Carousel, a ride that's almost a century old. It's enclosed in glass so it's good for any weather. Tickets costs $2, so it's not free ... but the view it comes with is!
Another popular art installation is the "YO/OY" sculpture by Deborah Kass. Find it near John Street in DUMBO, just under the Manhattan Bridge overpass.
My favorite part of this park is the Fulton Ferry Landing because it has the best views of the Manhattan skyline, and it leads to the Brooklyn Bridge.
There's also the Brooklyn Ice Cream Factory at the Fulton Ferry Landing — the perfect place to grab dessert with a view in the summer.
But the best part is this view.
