New Zealand's South Island is rich in glacier resources. There are many small airports in many places, such as the two sides of Mount Cook and Milford Sound, that offer helicopter sightseeing. According to the tour guide, New Zealand is one of the few countries that allows helicopters to land on glaciers. As the climate warms, it is not known whether restrictions will be imposed in the future. This project is also easily affected by the weather. Even if the sun is shining at the foot of the mountain, the weather conditions on the mountain do not allow it to fly, so please cherish and enjoy it if you are lucky enough to participate. Looking down at the glacier does have an indescribable beauty, and the moment you step on the ice sheet, many people will shout out in excitement, completely forgetting the not-so-cheap fee. Although you don't stay on the glacier for a long time, the wind created by the helicopter rotor is quite strong, and the ground is ice, not snow, so please take warm and anti-slip measures before departure.
