In its course within the Bronx Zoo, the Bronx River contains plenty of Hidden Waters materials such as a long-forgotten boathouse, a tributary stream, and a lake that flows into the river. At the Bronx River Gate to the zoo on Boston Road there is a walkway along its shore with a view of a waterfall that is open to the public free of charge.
It is a scenic and quiet corner of the otherwise heavily visited zoo, its centerpiece being a 10-foot cascade that appears as a waterfall.
