Housed in a stunningly decorated all-white space in the hip new Bauhaus-style annex of the recently renovated and expanded Kempinski Palace, the Rose Spa revives lovely Portoroz's raison d'être as a seaside resort—it was a fashionable spot for Austro-Hungarian grandees to take Adriatic dips and seawater- and mud-based cures in the early 1900s. Now the headliner in most treatments is the St. Barth product line, but staff still take a serious old-world approach to their work—and most have university-level training in sports medicine and physical therapy. Wind down after a 50-minute Klassik Rose Massage in the solarium, which has views over a gorgeous garden and the Mediterranean beyond, or paddle in the heated pool.
