Good sized waterfalls almost right at the center of town.
We're talking about the Bow Falls, which is right on the back door step of the Fairmont Banff Springs hotel. Simply take a hundred or so steps down the stairs to the falls. Of course you will have to take those hundred of so steps up the stairs, a much harder feat, back to your hotel room.
Not staying at the hotel, no problem, just take the drive down the road just before the golf course of the hotel, which winds down to a parking area. This is what I did, together with my bus tour party.
You can also walk from the Bow bridge, down the Bow Falls Path along the river, to the Bow falls area, full of benches, to watch the falls in all it's glory against a background of mountains. Unfortunately we couldn't see the mountains, as the whole place was filled with forest fire smoke, smog like it was downtown LA!
And finally you can take a raft like Robert Mitchum and Marilyn Monroe over the falls, in Otto Preminger's 1954 movie "River of No Return", in color. What some men will do for a damsel in distress!
We saw some rafting on the river, just below the falls -nobody would raft above the falls! That happens only in Hollywood!
