Trail Reviews
The kilometers from Arolla to Lac Bleu are quite steep and require some trudging. They allow you to avoid the more touristy path which leaves from La Gouille. Lovely surprises will be offered to the hiker, such as torrents, marmots and panoramas. The Blue Lake is splendid, it freezes your feet. The descent from Lac Bleu is done via the tourist path then follows a marked trail without much charm. It goes up the bed of the La Borgne d'Arolla river, passes through enclosures, crosses the river using the Monta Himalayan footbridge and ends with a beautiful climb.
The weather gods (or at least the person in charge) meant well with us. If autumn has already begun, you don't notice anything in Valais. At best you are at over 2000m. Then the night frost lasts until noon in the shady regions, and you have to be careful not to slip on a small piece of snow or ice, which would be very stupid on such a day. Right from the start it was a steep climb - you know that. A mountain trail with more vigorous ups and downs leads to the pretty Lac Bleu, which seems to be quite a popular body of water. Although it theoretically goes down to Arolla from there, the continuation of the Höhenweg is peppered with steep climbs. (I made the mistake of thinking this was a walk years ago.) But the sublime scenery of Mont Colon and the Pigne d'Arolla and their glaciers keeps appearing before us - rich reward for the effort!
