A short account of the Jordan River, given by your Israel & Jerusalem private tour guide
The person who expects the famous Jordan (Hebrew: Yarden) River to look like one of the large rivers around the world, will probably be disappointed. It is, in fact, a narrow and shallow stream, only 251 km (156 mi) long, supplying about 500 million metric tons of water per year. Its importance for the tourist is based on its historical and religious context. For the State of Israel, it serves as a major source of fresh water.
A bit of geographical information
The Jordan River gets its water from three main tributaries: The Dan River, the Hermon (Banias) River and the Snir (Hatzbani) River. All three rivers are fed from rainwater and snow that falls on Mt. Hermon, and reappears at the foot of the mountain as large springs.
