Montfort Nature Reserve. A 13th century Crusader castle lords over a channel of the Kziv River. The French name means strong mountain. This is one of the loveliest fortresses in Israel. A Crusader farm with attractive Gothic domes survives almost intact at the northern foot of the castle on the Kziv riverbank, and alongside it are a flourmill and the remains of a large dam that was used to store river water for agricultural purposes. The Kziv stream is one of the most beautiful of the northern streams and has a combination of flowing water and animals and forest views.
