Bull Hill, also unofficially known as Mount Taurus, is a mountain north of the village of Cold Spring on the Hudson River in Putnam County in the U.S. state of New York. It is part of the river-straddling range known as the Hudson Highlands. While not as well known as neighboring Breakneck Ridge or Storm King Mountain across the river, it too is part of Hudson Highlands State Park and has an extensive trail system and offers hikers sweeping views of the river and neighboring peaks from rock outcrops near its wooded 1,420-foot (433 m) summit, higher than both neighbors. A former quarry is visible on its south ridge.
