I've been up and down Access Cr perhaps a dozen times in the last 15 years. It has been my experience, contrary to popular belief, that the south side of the creek is an easier and more pleasant route for the initial climb into the hanging valley. Once you become familiar with the place, it is quite an easy route. I also now only use the upper valley when it is in snow. In summer I always climb to Access Ridge and traverse the spectacular crest north to Luna. Take some time to get to know the different possible routes in this area, you won't regret it.
