Come be awed by the Bronx River's beauty: bike with NYC H2O's Matt Malina & Leigh Wells to tour the river from Williamsbridge Oval to its source in Valhalla!

Did you know that the Bronx River is NYC's only true fresh water river? It was considered as a source for NYC's drinking water in the 1830's but was labelled "an open sewer" by the end of that century. The river has made a comeback since the days of reckless dumping and now supports many forms of aquatic life like Alewife Herring and even a beaver named "Jose."
