The unique wind tunnel with a round flying chamber with a 4.3 m diameter and a total height of 7 m was built in Slovakia, in close vicinity of the Tatralandia water park. The air flows at a speed exceeding 280 km/h. The two leg tunnel is powered by four fans. This tunnel was built close to the Tatralandia recreation center and it complements the relaxation possibilities on skis and in the thermal water park with another adrenaline experience. The tunnel was built leaning on a slope, with a high concrete tub, and its flying chamber is at terrain level of the main entrance.
