New York City is known for Central Park. The other parks get considerably less attention – and have considerably less public access.
Fort Totten, Queens
There are areas of the park that are accessible; namely, the athletic fields. The rest is crumbling abandoned buildings and a playground for the NYPD and FDNY. If you’ve ever wondered if it’s true that the NYPD is the 7th largest army, this might convince you that it’s true. Regardless, not a park.

Tottenville Shore Park, Staten Island
The locals were a little concerned about us, since we were clearly lost and in need of help. This is 100% vacant lot.

Riverside Park, Manhattan
If you’re south of the George Washington Bridge, this is a lovely place to jog or bike. North of the GWB and it’s a gay cruising zone in the Amtrak right-of-way. The water’s edge is still lovely, so if you’re interested in some nude sunbathing, this is worth checking out. Farther north the naked men are replaced by families out fishing near Dyckman Street.

There was a really embarrassed man hiding in the bushes a few feet away from me while I took this photo. He was horrified that I’d stumbled upon his nude sunbathing spot. Sorry, dude. Image by Cori Carl
Blissenbach Marina, Staten Island
I’ll give the Parks Department the benefit of the doubt and assume this was derailed by Sandy.
Garrison Park, Bronx
The New York City Parks Department doesn’t think this is a park, but Google Maps does. It’s a great place to play on some at-grade train tracks and create some art in the tunnel. It’s also conveniently located to Concrete Plant Park, which isn’t nearly as fun as it sounds. Update: Google rejected my map update, but they finally took someone else’s word for it.

Bonus: Liberty State Park, Jersey City, NJ
What do you do when a big chunk of land is full of toxic waste and owned by bankrupt companies? Turn it into a park and fence it off.
