Wilmot Pass

Wilmot Pass sits between Mount Wilmot and Mount Mainwaring and forms the land link between Lake Manapouri and Doubtful Sound / Patea. On the eastern side the Spey River drains to Lake Manapouri and on the western side the Lyvia River drains to Deep Cove in Doubtful Sound. The pass is notable for steep rainforest-clad slopes, numerous waterfalls visible from the road and its remote high-country feel.

The pass is named after E. H. Wilmot, an early surveyor who recorded the route in the late 19th century; European tracks and huts existed in the area from the early 20th century. The present 21 km unsealed road was built in the 1960s to move heavy equipment for the Manapouri hydroelectric project and remains the only road on the New Zealand mainland that is disconnected from the main roading network. The road passes several waterfalls, including Stella Falls, which are notable features along the route.

Visiting Wilmot Pass is usually part of a combined trip: boat across Lake Manapouri, then a vehicle transfer over the pass to Doubtful Sound for day or overnight cruises. The road itself is rough and remote with no services on the pass, so most visitors travel with licensed operators; the scenery is the main attraction rather than built facilities. There are also marked routes and old tracks for experienced walkers but these are remote, exposed and require alpine experience and navigation skills.

• Stella Falls and roadside waterfalls: Multiple waterfalls tumble down the steep slopes beside the gravel road, with Stella Falls one of the most visible from vehicle viewpoints.
• Panoramic views to Doubtful Sound: From higher points on the pass you get sweeping views towards Deep Cove and the rainforest-clad fiord valleys.
• Wilmot Pass road engineering: The unsealed 21 km road and its cuttings tell the story of 1960s hydroelectric construction and heavy-equipment transport.
• Mount Wilmot and Mount Mainwaring scenery: The surrounding peaks frame the pass and offer classic Fiordland backcountry vistas.
• Lake Manapouri approach: The approach across the lake and the shoreline transfer provide contrasting views of the lake, mountains and infrastructure related to the Manapouri power scheme (including underground tailrace tunnels).

The nearest settlement for services and departures is the village of Manapouri; most visitors begin trips from the Lake Manapouri shore. The nearest cities with airports are Invercargill (Invercargill Airport) and Queenstown (Queenstown Airport).

There is no public road link from the wider New Zealand network to Wilmot Pass: the usual route is by boat across Lake Manapouri to the lake terminal, then a licensed vehicle transfer over the unsealed Wilmot Pass road to Doubtful Sound; operators run combined lake-and-sound cruises and transfers. Independent access requires careful planning, water transport to the lake shore and arrangements for the remote unsealed road or long backcountry routes.

• Dress for heavy rain and rapidly changing conditions; Fiordland is very wet even in summer.
• The Wilmot Pass road is unsealed and remote - travel with a tour operator or a suitably equipped vehicle and experienced driver.
• There are no facilities on the pass itself; carry food, water and warm waterproof layers for transfers.
• Tours often combine a lake crossing with a bus transfer and Doubtful Sound cruise, so book transfers or cruises in advance during peak seasons.
• If you plan to walk any routes linked to the pass, treat them as alpine backcountry tracks and carry navigation gear and emergency equipment.
