Doubtful Sound is the second largest fiord in Fiordland National Park, in the south-western corner of the South Island. Its stunning scenery, with rugged peaks, lush rainforest and a glittering expanse of water, sits like a pearl in a setting of isolation and serenity. Doubtful Sound is 421 metres deep (the deepest of the fiords) and is long and winding, with many stunning waterfalls and hidden inlets waiting to be discovered. Fur seals, bottlenose dolphins and Fiordland Crested penguins can be seen on many of the small islets at the entrance of the fiord. The standard option for a visit to Doubtful Sound is to do a day trip, and go for a cruise, but there are several other options available if you have the time – one of the real highlights being to kayak through the Sound, and then camp there for a number of nights. (See, for example, Real Journeys, who offer kayaking and camping packages: http://www.realjourneys.co.nz ).
Getting to Doubtful Sound is an adventure in itself. With no direct road access, the only way you can to get to Doubtful Sound is by a cruise across Lake Manapouri and a coach trip over Wilmot Pass. This isolation makes the fiord a very special place, a place only those in the know get to see.
