Important both historically and economically, the beachside city of La Serena is one of Chile's oldest post-Columbian cities. The region's silver, copper and agriculture were so important that the city had its own mint. Today, La Serena maintains a colonial air, although it is threatening Viña del Mar's supremacy as premier beach resort. Apart from a string of beautiful beaches, attractions include a handful of museums and a number of nearby quaint villages and vineyards.

A moving sight...literally. Hubbard Glacier's recent nickname "the galloping glacier" refers to its rapid movement through Disenchantment Bay in the direction of the Gulf of Alaska. This tidewater glacier is a natural wonder over 6 miles wide! Those on ships are usually able to get within about a half mile of Hubbard Glacier's face.

Trebinje, the southernmost city in Bosnia and Herzegovina, sits just a short drive from the Adriatic coast but offers a completely different rhythm. Framed by hills and set along the Trebišnjica River, the city has a history stretching back to Roman times.
