The trail to the Schönbiel Hut offers breathtaking views of the north face of the Matterhorn, the Dent d’Hérens, the Zmutt and the Stockji glacier and more along the way.
The Glacier Trail Saas-Fee from Fellskin to Mattmark via the Britanniahütte, crossing the Hohlaubgletscher and the Alallingletscher, is one of the best day hikes in the Swiss Alps and one of my favourite day hikes.
The Grand Balcon Sud hike via Lac Blanc is one of the most popular hikes in the Chamonix valley and can get crowded on a sunny day in high season. Of course, it is popular for a reason.
