In reply to keeenclimber:
In summer the glacier is normally dry so reasonably safe to walk on provided you're happy walking on ice. There's a short section of easy scrambling to get off the glacier, there's a cable so you can clip a via ferrata leash to it if you're not confident.
I've only been there in summer so don't know how it would look by the end of October, but by this sort of time I'd expect the first snow to have fallen. This could mean hidden crevasses covered by only a thin layer of snow that won't support your weight. Snow on the rocky scramble section will likely impede progress too
If you're experienced in these sorts of conditions, especially crossing wet glaciers, it would be easy enough, but the fact that you're asking suggests perhaps not. I'd recommend waiting till summer. I suspect it wouldn't be all that enjoyable in the conditions you might encounter anyway.
