A-Rosa Travemünde

A two-level, 4,500-square-meter spa is the anchor here, with a Himalayan salt sauna, ice grotto, Turkish bath, and Kneipp pool covering most conceivable ways to sweat or shiver. This Baltic Sea resort also has beach access and all the sailing and surfing that comes with it, so the restless set has options. Rooms are bright and spacious, many with balcony views over the water, and the on-site Buddenbrooks holds a Michelin star if dinner calls for something serious.
