Our family is planning a trip to Banff this summer. We would like to bike some of the Legacy trail, but am thinking that Banff to Canmore and back is too much for our 9-year-old. Does anyone have experience with this trail? I don't want to just go one way because we have no cheap way to get ourselves and all the bikes back. Is there a portion of the trail that anyone would recommend? We are going to need to rent bikes, so we must be able to start from a bike rental place and return there easily.
