Your Doubtful Sound adventure begins as you cruise the crystal clear waters of Lake Manapouri. Then it's over Wilmot Pass, stopping along the way to experience some of Fiordland's densest rainforest and to view the colorful alpine moss gardens before joining the 3-hour Doubtful Sound Cruise that takes in the most dramatic scenery of Doubtful Sound.

You'll be picked up from your Te Anau hotel and travel to Lake Manapouri to West Arm. You'll board a coach and cross over the 670-meter high Wilmot Pass. You'll stop here to view Doubtful Sound far below. Your journey continues to Deep Cove where you'll board a spacious catamaran for a three-hour Doubful Sound Wilderness Cruise that takes in the most dramatic scenery of Doubtful Sound. The skipper will provide detailed commentary and point out highlights. Ten times larger than Milford Sound, Doubtful Sound is an unspoiled wilderness of many moods, one minute clear, blue and sun drenched, the next mysterious and mist shrouded. A wild place of dense rainforest, rugged peaks, cascading waterfalls and deep still waters quiet, serene and green.Keep a look out for wildlife as bottlenose dolphins frequently come alongside the vessel, fur seals bask on the rocks around the fiord and rare penguins can at times be observed.
