East River Secrets: NYC's Infrastructure by Ferry - Private

This is not a sightseeing cruise -- it’s a guided look at how New York City’s core infrastructure actually works. Led by a transportation planner and licensed NYC guide, the tour uses the East River as a moving classroom to explain the systems most people never see: trash movement by barge, wastewater and sewer outfalls, landfills that expanded the shoreline, rail and subway tunnels beneath the river, and the bridges that knit the city together.

Rather than focusing on landmarks alone, the tour connects everyday infrastructure to history and public health -- from Dutch-era dumping in Lower Manhattan to modern shoreline rebuilding, from working waterfronts and rat-shaping waste patterns to stacked train tunnels under the river. Guests experience rare, water-level views while learning how engineering decisions beneath and above the East River shaped New York as a city.

The result is an expert-led experience that reveals the hidden systems behind the skyline.
