Directions to Rucker Park
Rucker Park is in Harlem, on 155th street and Frederick Douglas Boulevard (8th avenue). In case you're from out of town, Harlem is in north Manhattan. But New Yorkers don't say "north Manhattan," we say "Harlem."
There are police outside the park, and a top notch security organization who searches everyone who enters the park.
Take the B train to the 155th street station (the stop is 155th street and 8th avenue) and you'll be one block from the park. The B stops there at all hours. The D train stops at this stop late in the evening.
Although you can also take the 1 or 9 train, InsideHoops.com very strongly recommends that you use the B/D train.
If for some reason you take the 1 or 9 train to 157th street, what sounds like a simple walk to the park is complicated by a highway, and takes about 10 minutes. You get off at 157th street and walk south, and when you reach 155th street, make a left and walk on 155th street. Right when you make that turn, you'll probably pass a gas station. Walk a few blocks on 155th street until you get to a bridge. Walk directly to the corner where the bridge starts, but instead of walking over it, walk left. You are now walking on the right side of the road that twists down a hill a bit to the right. It takes about two minutes to get the bottom, where you make a sharp right and walk along a broken sidewalk with bushes right around you, a highway to your left and a high wall and fence to your right. Keep walking for a minute and you'll be on a regular street. A block or two later, the park will be on your left.
Now you see why InsideHoops.com recommends you take the B or D to 155th, not the 1 or 9.
