I had been in Chamonix for a few days, and my Airbnb had a great little deck that overlooked Mont Blanc. On the near side of the mountain there was a massive glacier (pictures from a distance never do it justice, but it was impressive to see)
It was frustrating. Everything was closed. First the parking lot (I found a spot on the side of the road), then the trail (I translated the sign as best I could to understand that I could go partially up, but not all the way due to snow), I ducked the rope and went for it.
There's a mountain hut near the glacier and yet another chained off area with a sign I could kind-of read indicating that I shouldn't go further. There were people working on the hut and I managed to talk my way past them and get permission to go a little further.
I only had to climb up a few hundred yards past the hut before I got a great view of the glacier. It was impressive and surprisingly loud. It was pushing 70 degrees out, so the snow melt had created a river underneath the glacier. It was a pretty relaxing place to lie down for a while.
I took a grass road past some rural homes on the way down with some unreal views looking back toward Le Brevent.
