The nine islands that make up the Azores are in fact the peaks of some of the world's tallest mountains, reaching from deep beneath the Atlantic. The once-uninhabited, volcanic archipelago now hosts thousands of tourists every year who flock to the islands for sun, sand and verdant mountain scenery. From the beaches of Praia da Vitoria to the bustling marina of Horta, to the bubbling volcanic ground "ovens" of Furnas, these islands offer unparalleled--and unusual--adventures to discover.

The "Mother of Cities" was founded in 1537, and declared independence from Spain in 1811. The charming historic section can be explored on foot. The friendly Paraguayan capital, gateway to the grassy Gran Chaco region, has long been a centre of music, poetry and the arts, but only in recent years has Asunción been able to escape its long history of rule by dictators.

Amid a patchwork of sandy Mediterranean beaches, salt marshes, and flamingo-filled coastal lagoons, the water-locked town of Le Grau-du-Roi serves as a scenic gateway to the Camargue.

Though probably best known as the capital of West Germany from 1949 to 1990 (and of reunified Germany until 1999), Bonn actually has a history dating back to the 1st century BC. Roman soldiers were stationed here and the largest known Roman fort was built at Bonn. In medieval times, the town gained prominence when the Archbishop of Cologne transferred his seat to Bonn. The city's most famous son is Ludwig van Beethoven, born in 1770 at Bonngasse, where a museum now honors him.
