Set on a dreamy stretch of coastline on Montenegro's Boka Bay is the five-star One&Only Portonovi, a secluded resort with mountainous Adriatic vistas. This palatial paradise is a hidden gem, surrounded by the popular tourist sites of Croatia, Greece and Italy, but yet to be discovered by the crowds. The stunning location allows for fresh air adventures through sapphire waters, dramatic forests and medieval towns. With One&Only's signature bespoke service, wellness programs and exquisite dining in one of the world's dreamiest locations, this is a true paradise. Spend blissful days on the water, dine at Sabia al fresco restaurant (or any of the other three exquisite restaurants) or simply lounge poolside. For utter indulgence, the Chenot Espace spa is heaven on Earth for bespoke treatments and head-to-toe pampering.
