7The Azores, Portugal

Some say this volcanic island chain on the North Atlantic could be the next millennial hotspot.

UNESCO recognized three islands – Graciosa, Flores, and Corvo – as biospheres, and there are 13 Ramsar (important wetlands) sites and even more Blue Flag beaches. Those keen on sustainable tourism will love it, as will fans of whale watching, watersports and hiking. Mt. Pico, Portugal’s highest mountain, affords impressive sunrises and sunsets.
