There are two main entrances to the mas’aa from the ground tawaf area.

At the Black Stone Corner (al Hajar al-Aswad): Walk towards the mas’aa area starting from the Black Stone Corner and it will take you directly to the basement mas’aa

Behind the Maqam of Ibrahim: Walk towards the mas’aa area, moving towards the staircase on your left and it will take you to a basement area with a square tiled pavement on the right that inclines up to Safa – if you do not go up the incline and keep walking, you’ll end up in the basement floor mas’aa
