In reply to afshapes:
A word of caution, the state of the glacier can vary drastically year on year. Did a day trip on it back in July 2011 and it was a basic slow plod. Didn't rope up, but had full winter kit. There are a few crevasses you wouldn't want to fall into!!
Descended down in it August 2016 after doing a route, thought the summit was quiet, soon found out why!! The glacier was simply horrendous, not a flake of snow on it, just pure hard and smooth ice, with rock debris. Would have been impossible to descend without crampons, falling still not an option though! We only had one ice-axe between us, but it would have been extremely hard to arrest a fall.
Maybe best to recce the glacier first or use the Westgrat via ferrata as a descent route. There is some ice at the base of this, but it is only a remnant of a glacier and not that long.
If you do descend the glacier there's an entertaining open bucket lift from Pian Fiacconi to Passo Fedaia, it should be open daily to 5pm up to mid September and only cost a few euros
