This photo shows the Register Ridge trail climbing up and away from the Ski Hut trail. It goes between the two small trees you see here. It is rather faint. If all else fails, head directly up this ridgeline, and you'll find a path.

When you walk up the Ski Hut trail, you pass a register (hence name of trail) on your right hand side. COntinue until the trail makes a right turn. The Register Ridge trail will be on your right, directly in front of you.
