I had to look this up, as I have especially fond memories of the mountains in Switzerland. Grindelwald is the valley near the Eiger mountain. I spent much more time in Zermatt and was mistakenly remembering the Gornergrat. I don’t remember ever seeing an Alpine Horn in the early 1990s.
Grindlewald, one of the most beautiful of the high Alpine valleys, is about twelve miles long and four miles broad. It owes its celebrity as a resort for travelers to two great glaciers, branches, or arms, as it were, of the immense ocean of ice which covers the Bernese Oberland. The village of Grindelwald consists of a number of widely scattered cottages with about 3,500 inhabitants. There is probably no more popular tourist headquarters in Switzerland than Grindelwald. Not only does it lodge summer guests, but it enjoys a carefully planned winter campaign, which it really deserves. As the traveler approaches the village, spread out over the quiet valley, the surrounding mountains are often heard to echo and resound with the long drawn notes of the Alpine horn, blown by some enterprising yodler who comes into view as we round a curve in the mountainous ascent, and who now with great assurance demands a fee for his voluntary entertainment.
