Go Cruising on the Sound of Silence

No doubt about it. Doubtful Sound, also known as the Sound of Silence, is one of New Zealand's top nature attractions. It is the deepest (421 metres) and the second largest of the 14 fiords in Fiordland National Park on New Zealand's South Island, and three times longer and 10 times larger than the popular and more accessible Milford Sound.
