Curaçao
Curaçao, a Dutch Caribbean island, is known for its beaches tucked into coves and its expansive coral reefs rich with marine life. The capital, Willemstad, has pastel-colored colonial architecture, floating Queen Emma Bridge and the sand-floored, 17th-century Mikvé Israel-Emanuel Synagogue. It's also a gateway to western beaches like Blue Bay, a popular diving site.
