Southern Secret Cruises

Experience Fiordland at its very finest with our overnight & multi-day cruises on Doubtful Sound.

The Southern Secret is a purpose-built motor cruiser that offers overnight cruises and charters in Doubtful Sound. Stay in one of the five well-appointed, ensuite 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 try your hand at fishing or kayaking. 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 up close to waterfalls and other points of interest.
We would love you to join us & show you around these magnificent Fiords!
