Bash Bish Falls, a waterfall in Bash Bish Falls State Park in the Taconic Mountains of southwestern Massachusetts, US (Berkshire County, Berkshire Hills, the Berkshires), is the highest waterfall in the state. The falls are made up of a series of cascades, nearly 200 feet (61 m) in total, with the final cascade being split into twin falls by a jutting rock, dropping in an 80-foot (24 m) "V" over boulders to a serene pool below.
