8. San Juan, Puerto Rico
San Juan has it all: pristine beaches, farm-to-table dining, vibrant nightlife, and a buzzing art scene made up of galleries, museums, and murals that cover the city's walls.
Visitors can spend hours wandering through cobblestone alleyways framed by pastel-painted buildings and luscious greenery. The island was hit hard by hurricane Maria, but rebuilding efforts are underway.
