RealNZ · Doubtful Sound, via Manapouri
Doubtful Sound has no road in, so the day is a relay: coach to Manapouri, boat across the lake, coach over Wilmot Pass, then a long cruise on the fiord. Pick it over Milford if you want space and quiet more than the famous view.
RealNZ runs the whole chain. A coach takes you from the Te Anau lakefront to Manapouri, about 20 km away. A boat crosses Lake Manapouri to West Arm. Another coach climbs over Wilmot Pass, 671 m, through rainforest to the fiord, and a catamaran takes you out on Doubtful Sound. Then the whole thing runs in reverse. The listing gives 8.5 hours door to door.
The fiord is the reason. RealNZ describes Doubtful Sound as three times longer than Milford, with 40 km of waterways and no road anywhere near it. At a quiet spot the captain cuts the engines so you can hear the silence. Bottlenose dolphins, fur seals and, rarely, Fiordland crested penguins live here, though no sighting is guaranteed.
Two practical points. Lunch is not included: bring a packed lunch, or buy food on board, where it's cashless and cards are accepted. And the cruise length depends on who you ask: the listing says about three hours on the fiord, while RealNZ's direct page for the same cruise says about 2.5. Either way it's a long day, with steps onto coaches, a floating wharf and stairs on the boat. RealNZ sells the cruise direct from NZ$399 from Manapouri; GetYourGuide showed this version, with the Te Anau coach, from $215 at our last check.
Meet at the RealNZ Visitor Centre on Lakefront Drive. The coach takes about 30 minutes.
Cruise past the lake's islands to West Arm, at the far end.
Coach through rainforest and over the 671 m pass, down to the fiord.
Out along the fiord towards the open sea, with a nature commentary and an engines-off pause.
Coach, lake cruise and coach in reverse, about 8.5 hours after you left.

About 8.5 hours, according to the listing: 30 minutes by coach each way to Manapouri, an hour on Lake Manapouri each way, an hour over Wilmot Pass each way, and the fiord cruise in the middle.
No. Bring a packed lunch, or buy food and drinks on board. Payment on board is by card only.
Different. Doubtful is bigger, quieter and harder to reach, with a longer cruise. Milford has the famous peak and is a shorter day from Te Anau. For a first visit with one day, most people pick Milford; for a second fiord or a calmer day, Doubtful.
No. The caves are a separate RealNZ trip from the Te Anau lakefront. See the glowworm caves tour and book it for another evening.
