The Umayyad City Ruins in Aanjar, a UNESCO World Heritage site, offers a fascinating glimpse into an 8th-century trading town, showcasing well-preserved streets, palaces, and mosques. The site is generally accessible, largely flat with some uneven terrain, and easily reached by car or taxi from Beirut; while possible to visit solo, a local guide is highly recommended to fully appreciate its historical context, as signage can be limited. There are no seasonal restrictions beyond typical opening hours (usually 8 AM to sunset), but spring (April-May) and autumn (September-October) offer the most pleasant weather, avoiding summer heat. The approximate cost involves an entrance fee of a few USD (check local LBP rates on arrival), and a typical visit duration ranges from 1.5 to 2.5 hours. Visitors should wear comfortable shoes, bring water, and sun protection, especially in warmer months, as shade is minimal; it's often combined with tours to Baalbek and Ksara wineries.
