You have to take your snowshoes off when crossing the bridge. If you are coming from the cable car, it is best to put them on on the other side.

The best place to have a picnic or a little rest, the area of the wall is very cold, since the sun never shines and there is a lot of wind. But from where the photo was taken, it is quite well insulated from the wind and it is where the sun shines the most.
