Considered the largest in the world, the Eis Pavillon combines fascinating construction with a dash of kitsch and lets you look beneath the frozen surface of the earth. More than 25 feet below the ice pack, the cavernous facility provides an impressive view of the surreal, frozen environment inside glacial formations. Bring a coat or sweater—it's literally freezing down there. There are ice sculptures, exhibits on glaciology and crevasse rescue, and even a chapel-like room for meditation, concerts, and art shows. To reach the Eis Pavillion, take the Alpin Express or Felskinn cable car up to Felskinn before switching to the underground funicular—the world's highest (prepare yourself for a drastic change in altitude). It's free in summer with the Saaspass.
