Just got back from BC and Alberta 2 days ago, our 3rd trip to this part of Canada. Will post pics and a report ASAP. We spent 3 nights in Jasper, then drove the Icefields Parkway en route to Golden, BC.
Be ready, it is going to be crazy busy. On our last trip we hiked to both tea houses at Lake Louise. This time was more of a drive by as we spent most of our time in BC. We stopped by LL last Saturday and the crowds were outrageous. Honestly, we spent 15 minutes there and couldn't wait to leave. Peyto Lake, same thing. Not sure where you're staying, but getting an early start is highly recommended. Glad we spent our time in Jasper, love that town and it never seemed too crowded. Hiking is the best way to enjoy the Rockies if you get the chance.
