Just 20 minutes south of Te Anau, Lake Manapouri has long had the reputation as one of New Zealand's prettiest lakes. The lake is hemmed by high mountains and studded by many bush-covered islands; it’s 1,457 feet deep in parts. Cruises run several times a day to the head of the lake, where you can join a tour of the West Arm hydro-station, deep underground. West Arm is also the departure point for those traveling on to
Doubtful Sound, a stunning stretch of water, largely untouched by visitors. A connecting bus crosses you over the 2,177-foot Wilmot Pass before dropping steeply down to sea level at Deep Arm, the head of Doubtful Sound.
