One of the major points of reference in the Exodus route is Mt Sinai, where the 10 commandments was given. Sinai was also referred to as Horeb.
In the Bible, Mount Sinai (Hebrew: הַר סִינַי, Har Sinai) is the mountain at which the Ten Commandments were given to Moses by God. In the Book of Deuteronomy, these events are described as having transpired at Mount Horeb. “Sinai” and “Horeb” are generally considered to refer to the same place by scholars.
There are many locations offered to where Mt Sinai could be.
There is a mountain called Mt Sinai at the southern part of the Sinai Peninsula, also called Jabal Musa. However, it was only in the 3rd century was it started to be called Mt Sinai at Jabal Musa.
“The biblical Mount Sinai is identified in Christian tradition with Jebel Musa in the south of the Sinai Peninsula, but this association dates only from the 3rd century CE, and no evidence of the Exodus has been found there.”

One notable fact is Codex Sinaiticus, one of the oldest most complete Bibles in the world, was discovered there.
“The ancient library at Jebel Musa was the source of Codex Sinaiticus, one of the major Greek texts used to aid Bible translation.”
Mt Sinai (Horeb) was also where Moses saw the burning bush.
The story of Moses and the burning bush from the Book of Exodus is a well-known episode in the Old Testament. It is a decisive moment because God reveals his name to Moses: the first time he has spoken his name to anyone. Located on Mount Horeb (better known as Mount Sinai), the burning bush was on fire, but wasn’t consumed by the flames.
“The Burning bush was, according to the Book of Exodus, a bush on Mount Sinai which appeared to be burning without being consumed by the flames.”
Horeb was identified in Midian, which is east of the Gulf of Aqaba along the northwest Arabian peninsula.
William G. Dever states that biblical Midian was in the “northwest Arabian Peninsula, on the east shore of the Gulf of Aqaba on the Red Sea”
According to Ex 10:1, the Sinai wilderness was beyond the Egyptian border.
Exod 19:1 (KJV)
1 In the third month, when the children of Israel were gone forth out of the land of Egypt, the same day came they [into] the wilderness of Sinai.
Based on these evidence, it is most likely Mt Sinai was not in the Sinai peninsula, but in the Arabian peninsula.
