For one night we invite you to journey into Fiordland with us to Doubtful Sound/Patea & experience untouched New Zealand at its very finest.

The Southern Secret is a purpose built motor cruiser which offers overnight cruises in Doubtful Sound. Stay in one of the five well-appointed, en-suited cabins and enjoy the spectacular scenery in comfort. The overnight cruise ensures that you get to see more of Doubtful Sound and you have the opportunity to take part in fishing or kayaking activities on-board. There is time to relax and enjoy the scenery while keeping watch for wildlife such as penguins, dolphins and seals. The smaller boat experience means that we can get you right up close to waterfalls and other points of interest. We would love you to join us & show you around these magnificent New Zealand Fiords.
