While you can’t get off at the decommissioned subway station under City Hall, you can pass through for a look-see:

Still, although it’s not open to the general public, there’s a way in-the-know New York subway riders can still see this famous and beautiful architectural glimpse at the city’s past. The 6 train used to make all passengers leave the train at the Brooklyn Bridge stop, but no longer. If you have a little extra time, you can stay on the train and view the City Hall Station as the train makes its turnaround.

Where’s the secret here? I’m betting a few dozen 6 train snoozers per day wind up making this tour by oversleeping and missing their downtown stop. No biggie.
