Photo: Milford Sound, one of New Zealand's most famous tourist destinations
Milford Sound is a fjord in the south west of New Zealand's South Island, within Fiordland National Park and the Te Wahipounamu World Heritage site. Geologically, a fjord is a long, narrow inlet with steep sides, created in a valley carved by glacial activity.
In May 2008, Milford Sound was named the top destination in the world, determined based on the opinions of TripAdvisor's six million members, the world's largest online travel community, ahead of Cayo Largo in Cuba, Rhodes in Greece, and California's Lake Tahoe. Milford Sound topped the list of 100 global destinations.
