There are many places to view glaciers on New Zealand's South Island, but Fox Glacier is definitely one to recommend. After checking in, you can store your belongings, pick up your gear, and listen to a thorough safety briefing.
After the briefing, you'll take a shuttle to the airport to board a helicopter. About ten minutes later, you'll arrive at Fox Glacier itself. After walking on it for about three hours, you can't help but marvel at the beauty of nature, but also feel a sense of regret at how quickly the glacier is disappearing, making you cherish this trip even more.
