Ain el-Sabil is located in the Dakhla Oasis of Upper Egypt, 2.5 km southeast of the village of Ismant and less than 1.5 km southwest of the archaeological site of Kellis/Ismant el-Kharab. The site extends up to 390 m from east to west and up to 220 m from north to south. Although its original extent is unknown, it does not seem to have been a significantly large settlement, especially in comparison with the neighboring village of Kellis. Ain el-Sabil is currently delimited to the north, east, south, and west by cultivated fields, which are dangerously encroaching upon the archaeological area.
