When staying in Madinah and Visiting the Prophet's mosque, women, elderly mothers, and small children are best advised to look for hotels nearest women-only gates. These gates are located on the north side of the mosque.
The Rawḍah ash-Sharifah and the Prophet (peace be upon him) rest on the very south side of the Masjid An Nabawi. If you are coming form the the south, it is atleast 450 meters or 500 yards between Abu Ayub Al Ansari Road and Bab Uthman-Bin-Affaan (Gate 25). Therefore, planning ahead will save you a long walk.
