Thanks to Gillian for leading us last Sunday, on July 3. While driving from Park Royal to Squamish, we had the torrential pouring rain, as Gillian described. She was warning us that we might not be able to climb all the way up the upper section of the Shannon Falls at the beginning of the trail. it turned out to be a greet day. If you have time, please check my pics from the hike. http://www.flickr.com/photos/benrose/tags/uppershannonfallstrail/
