With water that reaches up to 28 degrees in summer, Lake Klopeiner See is one of the warmest bathing lakes on the sunny south side of the Alps. The ‘Kärntner Seenfitness’ [Carinthia lake fitness] programme is available at no cost to all overnight guests in the region. Between May and September, you can choose between various sports: mountain biking, stand-up paddleboarding, road cycling, hiking, swimming and snorkelling. You will be accompanied at all times by a professionally trained guide who is ready to share tips and tricks. If you would rather explore the gorgeous landscape on foot than bathe, you should stay in the ‘Sonnenwinkel’ region of Carinthia: the region’s highlights include Lake Klopeiner See and the Lavanttal and Rosental Valleys, as well as the Southern Alps panoramic trail and the Obir dripstone caves. A tip: visit the Karavankas geopark with its guided tours, such as one where you get to hunt for fossils in the Vellach riverbed.
