It's rather pricey but I would recommend a helicopter glacier landing. We did the Pilot's choice helicopter glacier tour. You land on two different glaciers - the glacier selections are up to the pilot and he knows which ones would be the better to see that particular day - and get to walk a bit. Our pilot did a marvelous job - he knew a lot as he worked for a geological survey company prior to his pilot job in Alaska.
On our second landing, we had champagne.
