I was lucky enough to go to Moraine lake. I don't know if you've been there recently, but the parking lot only holds 100 or so cars and fills up at 3 AM or so, and they barricade the road after that. There is a bus that runs from Lake Louise parking lot to Moraine, but they release tickets 48 hours before the trip and those usually sell out pretty quickly. Forget about buying a ticket the day you're there.

In my case, I was lucky enough to get there towards the end of the day. There weren't any bus tickets left, but some cars had left so they let me drive.

Thanks for the tips, will bookmark those for my next trip! In case you're in Jasper, I highly recommend the hike up to the Geraldine lakes, which are gorgeous. The trailhead is at the end of a rutted dirt road and I think I saw maybe four people the entire day I was there.
