Don't worry. It's not a big deal. If you walk where people normally walk it's not a problem.

But believe me, it's getting hotter and hotter and you wouldn't want to walk that much abyway.

Like the guys said, you can walk on the Corniche and where you see people walking for sport.

But no one here takes a walk for the sake of it. Unfortunately you just drive.

Enjoy yourself, and, Keep Walking!
