A beach-lover's paradise, this Caribbean island's interior boasts desert, but the coasts are filled with picture-perfect, powdery white sand and tranquil sapphire waters. With gorgeous year-round weather, it's always the right time to scuba dive, windsurf, snorkel, tee off, horse ride or hike. At night, enjoy casinos and Vegas-style shows. While Aruba displays hints of its Dutch influences (it's still part of the Netherlands), don't expect Old World reserve: the draw here is relaxation and fun.
