Sebkha Sidi El Hani is a salt lake 25 kilometers southwest of the city of Sousse and 25 kilometers southeast of Kairouan. The north side is completely tourist-free. There are no roads, only dirt paths, and half a dozen houses. From Sousse, take the smaller road to M'Saken and Knaïs. You'll see the lake from afar. There are many dirt paths leading to its shores. You can ride on it. The further you go, the more water there is. It's a truly fantastic place. I camped on its shores for the night.
