The line is only a sketch. Access up the riverbed varies with the river conditions.
Alternative sections of 4WD track climb the southern valleyside to bypass river crossings if flows are high. Slower but dry. No crossings of the main river are required but several sidestreams must be crossed, including The Growler. These were 'dry feet' crossings after 12hrs of light rain when I visited.

We chose to ascend the slopes to a point above Hidden Col; this then required descent to pass under the icefall from McClure Peak. It may be better to cross Hidden Col itself. Traverse to below the unnamed col and ascend steeply (there was a 15m rock step in Jan 2015 that required scrambling).

Straight forward snow and rock until a steeper section below a false summit. A short rock step required the rope to reach the summit.

Canterbury/Westland guide has a good description of this route. The descent to the Bettison Lake is straight forward until a final rocky buttress. Careful route finding was needed with some down-climbing. After the first 20-30m, the descent was by zig-zagging on good rocky ledges.
Bettison Stream is followed on TR before making an ascending traverse above the scrub. There is a large cairn on the ridgeline at the edge of the boulder field. Traverse the boulder field, there were not many cairns in 2015 until the latter parts of the traverse; don't be tempted to descend. The marker poles for the start of the track only came into sight about 50m above them. The track is steep but well marked.
