All above-ground metropolises harbor shadow cities beneath. A New York Times reporter spent five days on a subterranean urban hiking expedition, spelunking through NYC’s labyrinthine sewer system. His colorful travel journal details encounters with wildlife and “mole people.” Here’s how to go on an invigorating adventure into the unknown, without leaving city limits:
Tuesday, 12:36 a.m.

We inspect our exit point — a manhole in the middle of the road. Will Hunt, a bespectacled 26-year-old who is writing a book about the underground (“The last frontier,” he says, “in an over-mapped, Google-Earthed world.”) will serve as our spotter. Will’s job is to watch for traffic: ascending from the hole, we do not wish to be hit by a car. We are to communicate by walkie-talkie. Will ties a long pink ribbon to the inside of the manhole cover. Dangling downward, this will be our signal we have reached the end.
