Cairo is busy. Very. Cairo is bustle, hustle and hubbub, a riot of noise breaking out of a confusion of streets. It can sap your strength and give you energy. A city that works on sensory overload, from the cries of the muezzin to the clatter of coppersmiths; from the camel dung to cumin-scented souqs. Carts sell pyramids of produce, plaster-peeling alleyways shelter bustling, bubbling coffeehouses. A caffeine-jolt of a city, one that endlessly rewards bold exploration, and welcomes the explorer in its inimitable, breathless fashion. Take a deep breath, then dive in.
