"Descend into the Depths of an Eerie Glacier For pure exhilaration, try your hand at ice climbing. Expert guides from a variety of tour companies, such as Outdoor Interlaken and SkiAscent, take groups up and down frozen waterfalls, glaciers, and ice-covered rock slabs in various locations in the Alps. The great news is that you don’t have to be an expert to strap into the harness and rappel down those crystalline blue ice crevasses. SkiAscent in particular offers three levels of tours designed to limit the amount of instruction and maximize the climbing time."
