Schlossberg is a family-run three-star hotel in the centre of Badenweiler, directly beside the Kurpark spa gardens. Its 17 rooms come with balconies looking out over the Vosges Mountains, the Rhine Rift and nearby vineyards. Guests get a sauna, a warm breakfast buffet, a restaurant, a coffee shop, minibars, safes and 40-inch flat-screen TVs, and the Cassiopeia Therme baths are about a ten-minute walk away. Families are welcome, and there is parking, a tennis court and golf nearby. Review scores are consistently high across major booking sites. It suits travellers wanting a quiet spa-town base rather than city nightlife, and as a small property it has limited room availability at busy times.
