Southland
Population: 102,600
Southland, on New Zealand's South Island, is the country's southernmost region. It's known for Fiordland National Park, home to snow-capped mountains and fjords like the famed Milford Sound, which has high vertical rock walls and is traversed by sightseeing boats. The Milford Track hiking route runs between the sound and Lake Te Anau. Nearby, a subterranean cave network shelters glowworms and waterfalls.
