Starting at Raspberry Flat, this track passes Mt Aspiring Hut in the West Matukituki Valley and then climbs steeply to the Pylon and Cascade Saddle - be warned that this is a dangerous climb across snow-grass and should not be attempted in bad weather.

From Cascade Saddle, the track sidles the slopes above the Dart glacier, dropping to the river and finally to Dart Hut.

Proceeding up the Snowy Creek to Rees Saddle, the track then descends (steeply at first) past Shelter Rock hut and on down the Rees Valley to the Muddy Creek carpark.
