1. Take a walk around the Old City Walls
This should be on everyone's to-do list and it's no secret why. Climb the centuries-old fortresses originally designed to protect the city, and admire the rooftop view of the UNESCO-protected Old City.
TIP: It is easier to enjoy historical sites from high above before the temperatures hit their usual summer peaks; in the hot summer months, plan your city walls tour for early morning or late afternoon hours.
