The Gulf of Aqaba is on the east side of the Egyptian Sinai Peninsula, and is part of the eastern border of Egyptian territory. The Red Sea called in the Bible "Yam Suph" in Hebrew, 'suph' meaning 'reed', is more accurately translated as "border" like the reeds which grow on the edge or "border" of a river. So it's not Red Sea, but actually Reed Sea or Border Sea.
In the past there have been two proposed sites for the Reed Sea Crossing. One at the point of the Sinai Peninsula, called the Straits of Tiran, and the other half way up the Gulf of Aqaba at Nuweiba, Egypt, which is easily visible via satellite because of the very large beach that extends out into the gulf. Both sites have underwater land bridges that come up from the vast depths of Aqaba, where a large group could cross, but only Nuweiba has chariot fossils easily seen and filmed by divers in the late 1980s and 90s. So today, many consider the Nuweiba Crossing Site the de-facto standard due to this overwhelming evidence.
