The track leads up to the bushline, from where snowpoles mark the way through open tussock tops over the Rough Creek Saddle. The poles meet the track down the upper right hand branch of the Blue Grey River above Lake Christabel.
Lake Christabel can also be accessed from the west - see Lake Christabel tracks.
Access the track from Speargrass Flat, 10 km west of Lewis Pass on SH7.
Know before you go
Weather conditions can change rapidly, particularly on the tops. Rain can quickly make even small streams treachorous to cross.
