There really are no words to describe how the natural beauty you will see from the air above the Juneau icefield. This was not the tour we booked--we were supposed to go dog sledding, but the camp closed early due to high temps. We were rather disappointed about that; however, this icefield is still truly amazing. I don't know if other companies do this, but to their credit, Coastal gives their pilots the freedom to select their landing site. We ended up on the Norris Glacier. There were three members in my travel party and (other than the pilot) we had the helo to ourselves. When we landed at Norris, it seemed like we were on our own planet. We couldn't see, hear, or otherwise detect any other people. The ice stretched as far as you could see. Our pilot/guide was very knowledgeable and walked us around a bit to point out some features of the glacier. The views would be spectacular either way, but having it all to ourselves was a really unique and memorable experience.
A note if you have mobility concerns: my wife has knee troubles and I was a bit worried about her walking on ice. It was actually much better than the dog sledding on snow (which we did later in the day via a different company). They give you some spiked boot covers and the ice has texture (not like a frozen-over pond or puddle) so there is actually decent traction up there. The steps up into the helo are big, but moving around the glacier isn't bad at all.
