Tawaf is seven circuits around the Kaaba. Your guide should explain where to begin, how to keep count and how to follow the route safely. The area can be crowded, so stay attentive to your group and do not push to reach a particular point.
Ask about accessibility arrangements if you cannot walk the full distance unaided.
