North of the Pyrenees stands the ancient Carcassonne, a stone fortress that's faced sieges, endured the brutality of the Spanish Inquisition, and thrived as a center of wealth during the salt trade a millennia ago. Today, it's a protected sanctuary and an avian paradise for robust avocets, exotic flamingos, and more.

In the sunbaked plains of southern Spain, between Europe's only desert and the mighty Sierra Nevada, lies Alhambra, a magnificent Moorish palace of lush gardens and shimmering fountains. Join us on a sweeping tour of the wildlife within, including Iberian frogs, white-bellied hedgehogs, and more.
