Well this is the fun one you get to fly in a helicopter and they drop you at the middle of the glacier which is more interesting than the lower part and of course the heli copter cuts out all that walking.Fox Guides offer two heli hikes
The flying Fox Helihike is approx 4 hours long and has won lots of awards
the 2nd won is approx 9 hours long and is awsome
