The Narrows, Upper & Lower Bay
New York Harbor
From Lower Bay through the Narrows to Manhattan: the most storied harbor in the country.
Ships bound for New York pass Romer Shoal's double flash, run the channels of Lower Bay through the Narrows and turn up past Robbins Reef and Governors Island. Lighted, the harbor becomes a river of red and green leading to the tip of Manhattan.
