There are a lot of attractions you can see and do in this area, depending on the age of maybe kids that are traveling with you.If you start in Canmore Just visit the tourist info.They are very competent and like to help.They will supply you with the necessary maps and explain what is possible during these days.There are some easy hikes around Canmore and walking in town maybe nice ,too.For the Athabascar Glacier you should know that you only get it together with the skywalk and both together will take about 2,5 hrs...without waiting for your group to start.I don‘t know whether you can already book tickets and parting time online in advance.So, have a look.The Athabascar Falls are not at the same place but further on to Jasper.Visiting them is free, but to enter the Icefield Parkway you need a Parkpass anyway.Might be less expensive to buy one for the whole year(around 130 CAD as far as I remember from May) than to buy one for each day,depending on what you want to do in this time.You could try to see Peyto Lake or Lake Louise(very crowded if you are there after 11am) , stop at Lake Herbert. Johnston Canyon is interesting,too, if your kids are older than maybe four and able to walk a distance of about 5 km. Maligne Lake is Nice ,too, but the boat trip to Spirit Island can only be recommended on days with good weather.Ot is interesting for photographers. There might be some bighorn sheep , elks or black bears around, even on or near the street.But with the bears you should avoid to get out of the car to get photos.As at this time of the year the female have cubs, they are more aggressive. And of course...no feeding of any of the wild animals.The rangers told us that they normally have to kill a bear that was fed and attracted by people because otherwise they might be a danger to the people in winter, getting too near to their houses.
