2 Best Hotels in Ibiza and the Balearic Islands, Spain

"Oasis" springs to mind when driving up through family vineyards to this lovingly restored medieval monastery, reborn as a deluxe resort hotel. Weather permitting, meals are served on the poolside patio, with a beautiful view of the Tramuntana Mountains. However, an atmospheric lounge-tapas bar is also inside, decorated with an ancient olive press, stone arches, and thatched vaulted ceilings. Guest rooms have king-size beds and comfortable modern furnishings; bathrooms have huge shower stalls, jetted tubs, and towel warmers. The straw hats in the rooms left there for strolling the grounds in the summer sun are typical of the meticulous attention to detail at Son Brull.

If you can stomach the once-in-a-lifetime price, Ibiza's chicest wellness retreat, built seamlessly into the cliffs above Xarraca Bay (12 miles from Santa Gertrudis), rewards with unparalleled spa facilities, a longevity clinic, an infinity pool, and fresh fish served among century-old olive trees. It took 10 years to bring the concept to life, mainly to keep it in tune with the wild surroundings. Thatched roofs, dense planting, and up to 51% of power from renewables ensure there's substance to the unquestionable style. With multiple restaurants, a kids' club, and a schedule of holistic workshops, the resort lures singles, families, and those seeking a medical-grade approach to wellness. The only drawback is the big one—the cost.
