Sugarloaf Pass Track

Sugarloaf Pass Track is a hard out-and-back from Routeburn Shelter to a broad saddle between the Routeburn and Rockburn valleys. The first ten minutes follow the Routeburn Great Walk before a signed right turn onto the narrower Sugarloaf track. Plan on about 8 km return, roughly 700 m of climbing, and 5–7 hours. The map follows the pass route and turns at the saddle, before the track drops into the Rockburn valley. Some published outings describe about 10 km; check whether they include the optional off-track rise above the pass to nearby tarns.

The shared approach crosses the Route Burn swing bridge on an easy gravel path. After the junction, the track narrows and climbs steadily through beech forest over leaf litter, roots and rocks, with a stream crossing. Above the bushline the ground opens into tussock and can be marshy. Orange poles mark the upper route, but the line is less obvious there, so keep an eye out rather than following the clearest-looking ground. The steep rooty descent can be as slow as the climb. In winter, shaded sections can ice up; above the trees, the pass is exposed to bad weather.

Sugarloaf Pass is a relatively flat saddle with views into both valleys; the Routeburn side looks toward Lake Wakatipu and the Humboldt Mountains. For a photo, keep some tussock tread in the foreground and frame either valley beyond it. Tarns and a small knoll sit higher up, reached by an extra off-track tussock climb of about 100 m. The through-route continues downhill into Rockburn and toward Lake Sylvan; that is a different, longer walk with separate transport logistics.

Start at the Routeburn Shelter car park, reached by gravel Routeburn Road from Glenorchy. A walk account reports a shelter and toilets at the car park, but parking capacity, fees and water supply were not confirmed. Dogs are not allowed on the DOC track.
