Pika Trees offers is sustained glade pitch with many options.
Take either the Grizzly Express Gondola, or the Ptarmigan Chair and either head into the East Trees above or down the Pika Cat track.
Once you pass Raven on the Pika Track you will find a large area of trees below you.
This is the Pika Trees.
The area is quite large and you can enter from any point.
It doesn't really appear to be a run, but that's the great thing about Lake Louise.
You can explore pretty much everything on the mountain.
Enter the steep trees and find, on a good day, great sustained tree powder.
The descent is fairly long for a Glade area and will bring you back out at the Pika cat track.
A local favorite and highly recommended.
