Eigergletscher-Jungfraujoch, 3818 Grindelwald, Svizzera
The Jungfraujoch is a col in the Bernese Alps accessible by railway, ending at Europe’s highest mountain station. Highlights include views of spectacular mountain summits like the Eiger, Monch, and Jungfrau, and views of the large Eiger Glacier that nestles below them. The Sphinx observatory, one of the highest astronomical sighting stations in the world, is located here as well. Views are endless and pristine, though amenities are small with just a handful of restaurants. It’s a very long train ride from Zurich, taking about 4.5 hours, but the experience is unforgettable.
