Sannur Cave is a classic karst cave created by groundwater percolating through the Eocene limestone of the Galala Plateau. It is the best example of this type of cave in Egypt. As the water percolates downwards, excess calcium carbonates are deposited on the roof and floor of the cave forming spectacular stalactites and stalagmites of various forms. When a light is shone on them, they glitter like a wonderland. Above ground, there are deposits of the red soil (terra rossa) associated with such formations, as well as several swallow-holes (dolines). The cave is located at 10 km from the city of Beni Suef which is situated at a 2 hours driving distance from Cairo.
