Roaring Brook Falls, Scenic waterfall at Keene Valley, Adirondacks, United States.

Roaring Brook Falls is an 80-foot horsetail waterfall on West Mountain in southwestern Cheshire, Connecticut, formed as Roaring Brook drops over a wooded cliffside. It is among the tallest waterfalls in the state.

Arrowheads found near the falls show that Algonquian people used the area before settlers from the Connecticut Colony arrived. From the 17th century the land was cleared for farming and the brook powered a stream-side mill. By the late 1800s visitors from New Haven came to see the falls. In 1974 locals learned the property might be sold for development; by 1978 the Town of Cheshire and the Cheshire Land Trust had preserved the waterfall and surrounding forest.

Arrowheads found near the falls indicate that Algonquian peoples used the area before settlers from the Connecticut Colony arrived. In the late 1800s the falls became a local landmark, drawing visitors from New Haven to see the 80-foot drop.

A flat trail of about 0.3 kilometers leads to the base of the waterfall, while an additional path of about 0.5 kilometers reaches an upper viewing spot. Both routes are walkable and relatively easy to navigate.

In winter months the falling water freezes and creates icy formations that change throughout the cold season. These frozen cascades develop differently depending on temperature and moisture conditions.
