Take a train trip on the Canadian Pacific Railway
Spend a night in a private cabin on the train as you head into the Canadian Rockies. Wake up and see the peaks of the mountains come into view. Keep your eyes open for wildlife, as you are likely to see elk, bears, and bald eagles. Spend the next 4 days exploring the Rockies from Jasper to Banff, before boarding the Rocky Mountaineer train back to Vancouver.
