||Full directions are in the various guides. Sharplin Falls Reserve, where you start walking for Mt Somers, is about 1-1.5 hours drive from Christchurch or Ashburton. The walk to the Hut from the carpark will take approx 3-4hours at reasonable pace. The beginning and end of the walk are steep. There are several stream and river crossings but unless there has been recent heavy rain, you need not get wet. the climbing base, Pinnacles Hut, is still 20minutes to 1h+ from the crags, depending where you want to go.
