Ein Avdat

Ein Avdat (Hebrew: עין עבדת‎) or Ein Ovdat is a canyon in the Negev Desert of Israel, south of Kibbutz Sde Boker. Archaeological evidence shows that Ein Avdat was inhabited by Nabateans and Catholic monks. Numerous springs at the southern opening of the canyon empty into deep pools in series of waterfalls. The water emerges from the rock layers with salt-loving plants like Poplar trees and Atriplexes growing nearby.
