I spent a week in the Banff area snowboarding both Sunshine and Lake Louise. I found sunshine to be a bit smaller overall with more flat areas on the green runs. It had been described by others as confusing because of the numbering of every section of a run. I tend to just sort of look at the map and see how I can stretch out a run as long as possible. The problem with this method at Sunshine is that every place where runs meet up, it is flat and wide open. However, given that this was my first time this season, I probably needed those breaks to rest before moving on. Later in the season, I could see this getting on my nerves. Overall, I enjoyed it. A fairly nice small mountain with lots of snow. It snowed there every day I was in Banff and when they got snow, they typically got more than Lake Louise. I stayed in Banff and got the SkiBig3 ticket 4/5 days. This got me free rides on the bus up to the ski areas. This was easy and convenient. The bus was nice and given that I saw people slip-sliding all over the roads, I'm glad I did not rent a car. It's only about 20 minutes from Banff to Sunshine. Food prices were a little high, but everything in Banff is a little expensive.
