Ibiza may not be the biggest of Spain’s Balearic islands, but it's definitely the most famous. The energetic clubbing scene and easy Mediterranean climate have been drawing visitors for decades, earning it primo status as Europe’s party capital. Sant Antoni de Portmany is a main center of nightlife—its west end filled with bars, terraces, and revelers. The town of Ibiza is about more than just partying, thought, and offers a well-rounded cultural experience and riveting architecture, including the fortress area and cobbled streets of Dalt Vila, a UNESCO World Heritage Site. Yachts, speedboats, and sailboats are all part of the Ibiza experience; and they're the best way to visit the many caves and bays on the coastline. The rock formation Es Vedrà, off the west coast, is especially worth a visit; book a snorkeling tour for an up-close look and to learn the many legends surrounding the site. Also worth a boat trip (even better on a private, luxury catamaran) is the neighboring island of Formentera towards the south, with unspoiled beaches and crystal-clear water. For an amped-up time on the water, try scuba diving or parasailing; or for or a more-relaxed encounter with nature, head to a laid-back area such as Sant Josep de sa Talaia and the surrounding countryside. Ses Salines National Park and the nature reserve of es Vedrà are some of the most tranquil places in the area: a welcome respite from the intense party life that has become synonymous with the island.
