Our family of three (at time of travel ages would be 52, 51, and 16) plans to visit Banff National Park in the summer of 2019. We plan to spend 10 days on the Banff National Park-Icefields Parkway-Jasper trip. What I am wondering is whether or not people would advise adding Glacier National Park to the trip (adding days to the trip to allow for seeing GNP) while we are out there or if people think that would make for too exhausting of a trip. We are all reasonably active people-in decent shape. We plan to fly into Calgary Airport at the moment and then rent a car. Just curious what people would do themselves based on their experience traveling in these parks. Are two parks too much? I will post the question on the Glacier National Park forum too. Thanks for your thoughts!
