Tappan Zee, Natural widening of Hudson River between Rockland and Westchester counties, United States.
The Tappan Zee is a natural widening of the Hudson River between Rockland and Westchester County that extends for several miles. At its broadest point from Croton Point to Irvington, the waterway opens up into a spacious expanse of water.
Explorer Henry Hudson sailed into this section of river in September 1609, initially believing he had found a western passage to the Pacific. This early expedition marked an important moment in the mapping of the northeastern coast by Europeans.
The name brings together the Lenape Tappan people who lived here and the Dutch word zee meaning sea or lake. Walking along the shores, you notice how both influences shaped how people refer to this place.
The western shore is defined by steep Palisades rock formations, while eastern communities like Ossining and Tarrytown line the opposite bank. Access to the water is available from several riverside communities, with Nyack on the western side offering a good starting point for exploring.
The western side features steep rock cliffs that rise directly from the water and form a natural wall along the shore. These dramatic formations create a striking visual feature that sets this section of the river apart from surrounding areas.
