One of my favourite in the area is Balu Pass which starts just behind the information centre at the top of Rogers Pass. Along with some friends, we did it a couple summers ago. It is about 6 hours return and winds its way through a beautiful valley with all sorts of waterfalls and wildlife. Balu means Grizzly Bear and we did spot one across the valley. He saw us and wandered away into the trees. It is a hike you usually have to do with at least 4 people. Amazing views from the top especially.
This video will give you an idea of the hike.
