Gulf of Bahrain, Marine extension in Eastern Saudi Arabia and Bahrain.
The Gulf of Bahrain is a body of water between Saudi Arabia and Bahrain, part of the larger Persian Gulf system. The King Fahd Causeway spans this waterway with a series of bridges and roads linking the two countries.
The maritime boundary between the two nations was established in 1958, marking a key moment for regional organization. This agreement shaped trade routes and shipping lanes that continue to matter for both countries.
Traditional fishing and maritime work remain visible in the waters, connecting people to practices passed down through generations. These activities continue to shape how communities live and work on both shores.
Access to the gulf is possible via the King Fahd Causeway, which carries both vehicles and pedestrians between the two countries. Visitors should be aware that border checks are required and proper documents must be carried.
Within the gulf sits Passport Island, a small land formation that serves as an international border checkpoint. This spot is notable because it functions as a neutral zone for managing movement between the two countries.
