The Grosser Aletschgletscher, the longest glacier in Europe, has recently been designated a UNESCO world heritage site, in recognition of its importance and uniqueness. And this place is special. The first sight of this awesome phenomenon is something a world apart from those diagrams in geography lessons, because this thing is enormous, ancient and on the move. Not millions of years ago, but now. And right there, from horizon to horizon, not a distant tongue of snow and ice poking over a rock wall.
This hike makes a memorable circuit of the Eggishorn, traversing along the slope above the immense glacier, before looping back to take in Southward-looking vistas of the Monte Rosa range and the Matterhorn. It’s a relatively flat walk too, with not much climbing required at all. …
I like the elevation map posted on that site.
