Ghadames is one of the most remarkable places in Libya — a UNESCO World Heritage oasis town on the edge of the Sahara, near the point where the Libyan, Algerian, and Tunisian borders meet. It's about 600 km southwest of Tripoli.
The old city is built entirely of mud brick and palm wood, with whitewashed interiors and a system of covered alleyways and passages that keep the interior cool in summer. Its most distinctive feature is the network of rooftop walkways connecting every house at upper level — traditionally the domain of women, allowing movement between homes without descending to the male-dominated street below. The entire old town can be explored on these rooftop paths.
Ghadames was an important waypoint on trans-Saharan caravan routes for centuries, and traces of Phoenician, Roman, and Byzantine occupation have been found here. It was once the southernmost outpost of the Roman Empire. The town was inscribed as a UNESCO World Heritage Site in 1986.
The journey from Tripoli through the Nafusa Mountains and across the Hamada al-Hamra plateau is itself worth the trip. Plan at least two nights here. It can serve as a southern detour en route to Sebha and the Fezzan, or as a destination in its own right.
