Eilat's Coral Beach, a northernmost shallow-water coral reef, is in which gulf?

Eilat’s Coral Beach is in the Gulf of Aqaba.

The reef lies beside Eilat, Israel, at the northern end of the Red Sea. The Gulf of Aqaba—also called the Gulf of Eilat—extends between the Sinai Peninsula and the Arabian Peninsula, with coastlines belonging to Egypt, Israel, Jordan and Saudi Arabia.

Eilat’s shallow-water coral reef is notable for being one of the northernmost such reefs in the world. Its protected coastal reserve covers about 1.2 kilometres of shoreline and supports corals, reef fish and other Red Sea marine life. The main Coral Beach Reserve was established in 1964.

The most likely confusion is with the Gulf of Suez. The two gulfs split around the Sinai Peninsula: the Gulf of Suez lies to the west, while the Gulf of Aqaba lies to the east. Eilat is on the eastern gulf, across the water from Aqaba in Jordan and near Taba in Egypt.
