The oldest university in the world isn’t Oxford or the Sorbonne—it’s the University of Al-Karaouine, and you’ll find it in Fes el Bali. This walled city, a UNESCO World Heritage Site, will transport you back to mediaeval times. Visit the ancient maze-like quarters of the Medina to Fes el-Bali and the four imposing Gates of Fes, with their distinctive Moroccan tile work. You can walk, or, if you're brave, take a taxi—the daredevil drivers will have you hanging on for dear life.

A gracious contrast to Old Delhi's winding streets, the grand avenues and stately buildings of New Delhi are rich with history and culture, from Gandhi's Delhi home (and the site of his assassination) to the tomb of Humayun, a complex of Mughal buildings reminiscent of the Taj Mahal. Chaotic traffic is best left to the locals. Negotiate a good price for taxis or travel on the new Delhi Metro.
