The Balearic island of Ibiza is famed for dynamic nightclubs and highflying bars, but it's also home to beautiful beaches, sandy coves and quiet hillside villages. A favorite vacation spot for cosmopolitan tourists, Ibiza is filled with history and culture. The entire island is a UNESCO World Heritage Site -- consider exploring the archaeological museum and its Phoenician artifacts or visiting Ibiza's historic cathedral with its 13th-century belfry.
