We had done our research and arranged to do the Dog Sledding and helicopter to Herbert Glacier with Coastal. Unfortunately that fell thru due to weather (we had read the other reviews and knew this was a possibility). Coastal worked with us to arrange for us to still tour the lower part of the glacier and wow, the whole family said it was the highlight of the trip!
The ride up was about 20 minutes and included a good tour of the lower portion of the glacier before we landed.
The time on the glacier was about 20 to 25 minutes (which was enough time due to the cold). We got to taste the glacier water, explore the glacier and learn a bit about it.
Our pilot Dan was awesome and very knowledgeable about the glacier and handled the helicopter with ease.
Would definitely recommend this trip to anyone looking to get away from the crowds at Mendenhall.
