Probably these are the nearest thermals to the airport of Munich and to Munich itself. The thermal complex Aquariush Swimming Pool & Sauna is situated in 17 minutes drive from the airport and in 19 minutes drive from the Olympic park of the city. In spite of the vicinity of the capital of Bavaria this is a full thermal complex with pools, saunas, a fitness center, though, its size is smaller than the sizes of the other complexes in this section. The water to the pools is supplied from a well 2 km depth, the sulfur thermal waters are especially recommended for the restoration of the musculoskeletal system.
