I heard about this climbing wall about a year ago. I had the chance to find it today with Mrgoon. We decided to leave a cache, so more people will know about it. The view is great, and looking down gives you a good feeling.
Easy hike to Mont-Shana. Start climbing the most left ski slope to the trail head. The trail is mark to the top of the wall. The difficult part start when you have to get down to find the cache. Enjoy!
