Yes, upon landing at the King Fahd Causeway, which links Bahrain and Saudi Arabia, you may obtain a visa for Bahrain. What you should know about getting a visa upon arrival is as follows:
Gulf Cooperation Council (GCC) nationals do not need a previous visa to enter Bahrain. When arriving in Bahrain from Saudi Arabia, citizens of GCC nations can apply for a visa at the airport or via the King Fahd Causeway.
Electronic Airport Visa: This is a three-month valid, multiple-visit visa that Bahrain and Saudi Arabia have authorized. Each visit cannot last more than two weeks. SAR 270 is the price.
King Fahd Causeway Visa: This visa costs SAR 150 when you enter the causeway and is good for one week. For an extra SAR 400, you may have it renewed every week.
By enabling prepayment of bridge crossing costs, the King Fahd Causeway Foundation offers an electronic payment option that makes it possible to use the bridge without having to wait in line at the gates. The King Fahd Causeway app may be used to enable additional features including dedicated lanes for quick crossing between the two nations and a variety of payment options.
