Cairo, Egypt

Capital City

While Cairo boasts a storied history and cultural riches, the harsh reality is that this megacity of nearly 6 million people is a chaotic mess of traffic, pollution, and bureaucratic headaches. The air quality is twelve times worse than WHO safety guidelines, and the city's infamous congestion frequently reduces major arteries to a sluggish crawl. But for those undaunted by the city's challenges, Cairo remains a vibrant hub of commerce, media, and ancient wonders.
