A demanding alpine route to Angelus Hut beside a glacial tarn.
Overview
From Coldwater Hut, this is a 9.4 km (5.8 mi) one-way point-to-point tramp to Angelus Hut on the shore of Lake Angelus. DOC allows six hours each way. The route climbs from about 620 m in the Travers Valley to a 1,650 m alpine basin; the last push above the bush edge is steep. This suits fit, experienced trampers looking for a serious hut approach. If you turn around at Angelus, you are signing up for 18.8 km and roughly 12 hours on foot, so an overnight stay makes more sense for most people. Book a bunk before you go; Angelus Hut requires bookings year-round.

Trail guide
Coldwater Hut is the start of this route, not a road-end trailhead. From St Arnaud, reaching the hut is another 12 km and about four hours on foot. From Coldwater, follow the Travers approach for about two hours to the Cascade Track junction. DOC also describes a Lakehead Hut approach to the same junction, but that route crosses the unbridged Travers River; the line here follows the Coldwater version.
At the junction, turn onto Cascade Track. DOC allows about four hours for the steady climb alongside Hukere Stream. The track ends at the bush edge, where the route leaves the formed path and continues on poles and cairns. Hukere means “cascading waters,” a good fit for the stream beside this long climb.
The crossing deserves respect. The bridge over Hukere Stream is removed from May to November because of avalanche risk. After rain or snowmelt, DOC warns that crossing the river can be difficult. This is a recurring seasonal issue, not a place to push on when the water is high.
From the end of the track, follow the steep poled route to Angelus Hut. Poles and cairns mark the way, but snow or cloud can hide them. DOC warns that the alpine routes can change quickly, with snow, ice, avalanche terrain and sub-zero temperatures. Winter and spring need alpine skills and the right equipment; allow extra time in those conditions, when this route can take up to nine hours one way.
Angelus Hut sits at 1,650 m beside Lake Angelus. DOC describes the lake as a large alpine pond or tarn shaped by recent ice advances. In most years the basin freezes and snow covers the routes from May to October, so a summer lake photograph gives only one version of this place.
The serviced hut has 28 bunks, toilets and mattresses. Its water comes from the lake and must be treated; from May to October, hut water and firewood may not be available. There is no dog access in the national park. If you are staying, confirm the hut booking and current facilities before you leave St Arnaud.
The valley has a travel history older than its marked tracks and huts. DOC’s park history notes that Māori knowledge of pathways and bushcraft helped early European explorer-surveyors enter the Nelson interior. In the 1840s, William Fox travelled with Māori guide Kehu and continued up the Travers Valley. That is valley history, not evidence that today’s marked Cascade route follows their exact line.
