The Eisriesenwelt [ice-giant world], at an altitude of over 1,600m, high above the Salzach Valley, is the largest ice-cave in the world. The guided tour takes visitors just over a kilometre, with a difference in height of 134m. The temperature is always around 0°C. 1,400 steps lead through the huge caverns inside the Tennengebirge emerging into a wonderland of magical natural sculptures. The only light comes from the visitors' carbide lamps and from magnesium strips occasionally lit by the guide to show the extraordinary ice formations. The cave was first explored and described by Anton Posselt in 1879. Now visitors number around 170,000 annually.
