Bahrain Island, or al-Awal Island, is the largest island in the archipelago. Its area corresponds to a huge percentage of the national territory. It also houses the majority of the population of the entire country.
Most of the seabed adjacent to the island is rocky and shallow, located in an inlet of the Persian Gulf known as the Gulf of Bahrain. It contains a strip of fertile land near the northern coast, where dates, almonds, figs, and pomegranates are grown. Inland is the highest point on the island, Mount Jabal ad-Dukhan at 134 m above sea level, named after the mist that often covers its summit. Most of the oil wells are located in its vicinity.
The island is connected to Muharraq Island by three viaducts. The 27km-long King Fahd Causeway connects the island to Saudi Arabia via Nassan Island.
