In Azores, you might spend your days hopping from island to island: Free diving, waterfall rappelling, volcano hikes and whale watching are everyday happenings here. You can also explore ancient fishing towns, manor houses and 15th-century churches. Stunning manors and chapels — plus an underground lake — dot the island of Graciosa. Many islands have been named after their natural elements, like the “Mountain Island,” which is also called Pico, or the “Flower Island,” which is also called Flores.
