Highest Drop 30m
Time 7-8 hrs
Grahams stream is a steep, vertical alpine descent. Its access off the Mt Aicken Track makes this a classic Arthur’s Pass canyon. The canyon features a series of 18 near back to back pitches. While no pitch is overly difficult, you need to be able to rig efficiently and have good natural anchor rigging skills.
First partial descent by Lindsay Main et al during a SAR team search, approx 2010.
First Canyoning descent, James Abbot, Nola Collie, Grant Prattley Steve Walker April 2019.
