Hotel Cala Saona & Spa

When it comes to Spanish islands in the Mediterranean, Formentera isn’t the most famous one. But Hotel Cala Saona makes a strong play for those seeking a polished luxury-resort experience — and perhaps a little more peace and quiet. With direct access to the island’s stunning beaches, the hotel also offers a tennis court, lavish spa, gym, massive lap pool, and full-service restaurant and bar with magnetic views of the ocean. Rooms match the seaside vibe with an airy white-on-white palette and floor-to-ceiling windows that let in plenty of light. The best suites come with outdoor jacuzzis that face the mystical island of Es Vedrà.
