The helicopter tour offered a spectacular view, and the blue ice caves on the glacier were stunning. Our guide, Hunter, was incredibly professional and humorous, leading us through the ice caves with complete confidence. The equipment provided was also excellent. Although the price was a bit high, it's a highly recommended experience.
The helicopter tour alone is excellent value, and the glacier hike takes almost 2 hours in total, offering a wealth of information about glaciers! Highly recommended!
