Where two and a half metre tall ants inhabit the forest, countless treasure chests dot the trail and giant dragons zoom overhead, hiking simply can't be boring. Healthy exercise, enjoyment of nature and endless recreational fun are cleverly combined at the Hög Adventure Park, the Serfaus Adventure World, the Fiss Summer Fun Park and on Thomas Brezina's "Adventure Mountains". And the icing on the cake: The SUPER. SOMMER. CARD. can be used free of charge on the mountain railways while you can also take advantage of other free offers and discounts.
