Angelus Hut via Pinchgut Track and Robert Ridge Route

Angelus Hut via Pinchgut Track and Robert Ridge Route is a 12.2 km, one-way point-to-point tramping route from Mount Robert car park to the hut on Rotomaninitua / Lake Angelus. DOC allows six hours in ordinary conditions. It is the most popular of four approaches in fine weather, but this is an alpine route with a long exposed ridge, not a casual walk. Plan your return or onward route before leaving: this entry describes the approach to the hut only.

From the car park at about 880 m, Pinchgut Track climbs steeply in zigzags up Mount Robert's north side. Beech forest grows shorter near the tree line, around 1,360 m, then gives way to open tussock. The gradient eases onto a broad ridge. Poles lead past Relax Shelter and the junction with Paddy's Track. There is no shade up here and no water along the route, so carry enough from the start.

The route follows the upper edge of 2nd Basin, where the old Mount Robert ski field buildings are visible, then crosses Flagtop at about 1,690 m and skirts 3rd Basin. The smooth-looking ridge does not stay smooth underfoot: larger boulders mark the southern end of the basin, followed by a rough sidle below Julius Summit. After that, the ridge narrows above tarn-dotted 4th Basin. Loose rock and short, careful steps slow this section. The high point is close to 1,800 m.

From the Speargrass Valley saddle, a short climb brings the first full view into the glacial basin. Rotomaninitua / Lake Angelus, smaller Hinapouri Tarn and the hut sit below the surrounding peaks. Follow the poles down the rocky slope to the lakeshore. The basin view is the route's signature scene; from the overlook, include the hut and both tarns to show how the buildings sit in the wide bowl.

Robert Ridge is exposed for nearly 10 km, with little shelter from wind or poor visibility, and sharp rocky sections that need steady footing. Those hazards can occur in any season. From May to October, DOC warns of snow, ice, avalanche risk and below-zero temperatures; heavy snow can stretch the journey to nine hours. Check the alpine forecast and current road access before setting out. The road gate may be locked when icy.

Carry all drinking water for the walk. Water from the hut's tap is untreated and may be unavailable in winter. Angelus Hut has 28 bunks and requires a booking year-round; dogs are not allowed on this route. Ice shaped the steep walls, sharp ridges and lake-filled basins here, with the last major glacial advances ending about 10,000 years ago. Julius von Haast made the first recorded scramble along Robert Ridge in 1860, though he may not have been the first.
