The southern alps in New Zealand is where you used to be able to hike up to glaciers. As a result of global warming, the glacier terminal has retreated so far that it is no longer possible to walk up to it. Eighteen thousand years ago, the glacier reached as far as the Tasman Sea based on moraines found in the area, but now it ends more than 10 miles from the coastline. There is the option to helicopter up to the glacier (which is heavily advertised in the area), but does anyone not see the irony in that activity?
When we finally reached the viewing platform, we were still a good distance away from the glacier terminus.
If you are able, this trail is definitely a must do if you find yourself in the area.
