"The hanging balcony overlooking the Sahara Desert"—that's how Tunisians call Tamerza, the largest mountain oasis. The height of the waterfall is 5 meters. It's well-known for the spectacular views and blue color of the water.
The best time to visit the waterfall is winter or spring when the amount of water is really impressive. In wetter times, the falls make a pool large enough to swim in—a rare opportunity in such an unfertile land. You can also learn about the old city history near that wild nature area.
