Ten times bigger than Milford Sound the mighty Doubtful Sound is the 2nd largest and at 421m the deepest of the southern fiords.
Inaccessible by road from Te Anau, the journey to Doubtful Sound begins with a boat cruise across Lake Manapouri. A bus ride then takes you over the Wilmot Pass and on to Deep Cove where the Magnificent Doubtful Sound awaits you.
There are many ways to experience Doubtful Sound - by kayak or cruise, as a day trip or on an overnight experience.
