From the information that can be gleaned from Exodus 15:23, 16:1, and Numbers 33:9-11, Elim is described as being between Mara and the Wilderness of Sin near the eastern shore of the Red Sea.
Thus, Elim is generally thought to have been located in Wadi Gharandel, an oasis 100 km southeast of Suez.
Professor Menashe Har-El of Tel Aviv University (1968) has proposed Elim to be the ʿUyūn Mūsa "springs of Moses", now in South Sinai Governorate, Egypt.
He noted that in 1907, the geologist Thomas Barron had observed that twelve springs existed at this site along with date palms.
[2] Exodus 16:1 records that the Israelites left Elim "on the fifteenth day of the second month after their departure from the land of Egypt", heading towards the biblical Mount Sinai through the Wilderness of Sin.
