Al-Ahsa Oasis, located in eastern Saudi Arabia, is one of the world’s largest natural oases, renowned for its lush palm groves, freshwater springs, and ancient irrigation systems. Spanning a vast region, it supports over three million date palms and diverse agriculture, sustained by a network of springs and canals, some dating back thousands of years. A UNESCO World Heritage Site since 2018, Al-Ahsa blends cultural heritage with natural beauty, featuring historic sites like Qaisariya Souq and Al-Qara Mountain caves alongside modern developments. Its unique ecosystem and centuries-old traditions make it a vital center for agriculture and tourism in the region.
