Hotels are taking the plunge like never before, many adding or fine-tuning breathtaking pools that are becoming destinations unto themselves. With new high-tech system options, stylish architecture and extraordinary views from which to wine and dine in high (some literally!) style, the following beg guests to get their feet wet all over the world.

Hotel Caruso, Italy: Guests at the Hotel Caruso can bask in the Mediterranean sun by the famed infinity pool perched 1,000 feet above sea level that appears to be seamless with the Amalfi coast. Jackie Onassis and Greta Garbo both lounged here (among others) and French poet Andre Gidé described it as “between the sky and the sea.” With Bellinis and fresh seafood on hand throughout the afternoon, why leave?

Ubud Hanging Gardens, Bali: Each of the 30 villas at Ubud Hanging Gardens has a private heated plunge pool terraced into the hillside overlooking the Ayung River. The pools have been designed to mirror the surrounding elevated rice fields, while 180º views of the valley extend to the sacred temple beyond.

Perivolas, Greece: Truly one of the most magnificent settings on Earth. The infinity pool, 500 feet above the glinting blue Aegean Sea, is the perfect place to take in one of Santorini’s famed sunsets.
