I had a great time taking photos along the Panoramaweg across the Gornergletscher to the Monte Rosa hut. I didn't make it to the hut, that will have to wait till another time.
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.
