THE NETHERLANDS Of course, cooking is a vivid experience for the nose too, as is every inhalation at the Keukenhof tulip festival in The Netherlands. Some say the park of Keukenhof - known as the "Garden of Europe" - is the most beautiful in the world: nearly 80 acres exploding with tulips, hyacinths, daffodils and other spring blooms in every color. You can stroll among them, inhaling the sweet scent of millions of flowers. SPAIN Accompanied by a local expert, you'll see centuries of history and culture preserved in its old town center. Nine hundred years ago, this area served as the frontier between Moors and Christians; it's best experienced by meandering the narrow streets, surrounded by the sight of house fronts and their medieval doors. Perched high above town, spot the Biar Castle on a rocky hillside. Continue your wandering in this Muslim-era fort and see its unusual 12th-century dome up close. TRAVELER SPRING 2019 19
