It's an island that runs parallel to the upper east side of the city. There is a tram that goes to the island that leaves from 59th street (that's the best part) and it just costs a subway ride on your metro card. It's a nice walk around the island and there are places to sit down as well as a Starbucks in the middle. There are people there all the time so there are no yichud problems.
- Don't come here on a cold night.
- It is possible to drive to the island, over the Roosevelt Island Bridge. Parking is nearly impossible. 
Hours Subject to change. Always verify.
All night. I think the trams run until 2am
