Have you ever stared longingly at the Brooklyn Bridge and thought, I wish I could climb that? Brooklyn Boulders, an 18,000-square-foot refuge for the urban climber located near the Gowanus, is happy to give you a shot. In addition to providing massive synthetic boulders, 360-degree climbing rooms, and 30-foot walls, Brooklyn Boulders even has a mock-up of the Brooklyn Bridge for patrons to exercise dreams of climbing local monuments. A Learn the Ropes class for beginners costs $75 and includes two day passes and rental gear. But perhaps most attractive to the skinny-jeans crowd (and youll see a lot of them here on the weekends) is the dance-club-volume stereo system that cranks out rock while you get in shape.
