I went there a couple of weeks ago and was told the best time to go for views was March-April when the clouds move off. I was with a tour party of five and we found the trip extremely disappointing. The place was drowned in low cloud and tourists. The cable car (our guide took us on) went up to the Yak Meadow (very disappointing - 30 minute flat walk and no view of the mountain). I wish I had done some research on this venue to find out about the glacier, but I doubt our lazy tour guide would of let us go there.
