South Lebanon has a population of 590,000 inhabitants and an area of 929.6 km2. The capital is Sidon. The lowest elevation is sea-level; the highest is 1,000 meters.

The governorate has several rivers: the Litani, Deir El Zahrani, Naqoura, Awali, Qasmiye, and Hasbani. The area is famous for its citrus and banana farms. Its main cities are Sidon, Tyre and Jezzine.
The area offers a great number of attractions, including pristine white sandy beaches south of Tyre, and the opportunity to snorkel or dive among submerged Phoenician and Roman ruins near the ancient cities of Sidon and Tyre. Culture-lovers will enjoy the bustling Ottoman-era Pazars, and one can relax after a long day at a seafood restaurant overlooking the Mediterranean. Southern Lebanon also hosts the Tyre festival, which attracts thousands of tourists each year.
Shias make up the majority of the governorate and are the main residents of the Zahrani Tyre districts. Sunnis are the main residents of Saida the capital of the governorate and the third largest city in Lebanon after Beirut and Tripoli. Christians are mainly residents of the Jezzine district and form a small community in the city of Tyre, which is the fourth-most-populous city in Lebanon.
