Took a visiting friend from the UK on some touristy trips from Calgary and we did the Skywalk, Columbia Icefields, Banff Gondola, Drumheller, Frank slide, Head Smashed-In Buffalo jump etc. Of all the spots, the Skywalk was pretty well the only one I'm not in a hurry to revisit. It truly was a one and done type of thing, and I'm usually fine with heights.
Regardless of my personal opinions, it's pretty neat and should be on one's bucket list if visiting the area. We did a trip north to the Peace Country in July, and it was amazing to see how few cars were on the Banff-Jasper route, and although that was great for us, I recognize the financial impact on the tourism industry. I've never seen Jasper so quiet on a beautiful sunny day. I wished I'd taken my bike and had allowed for some time for cycling, but that was not in the cards.
