Bordered by the majestic sand dunes of the Idehan Ubari to the north, and the Idehan Murzuq to the south, the Wadi al-Hayat is one of the largest and most fertile valleys in the Libyan Sahara, and is up to 12 km wide in places. Scattered along the oasis are villages and small towns surrounded by fields, market gardens and camel grazing, and the remains of Garamantian tombs around 2,000 years old.
