My husband and I will be staying for a week in Banff the first full week in July. We are in our late 20's, pretty good shape, and some hiking experience. We are looking to hike each day, and with there being so many different hikes, we were hoping for someone to help us narrow it done. What were your must do hikes? We are open for anything. Also-we have rented a car so we will have access to many places. And is it worth booking a day trip to Lake O'Hara?
