This is somewhat of a hidden gem as many people don't know about this impressive hidden canyon along the Icefields Parkway, but it's actually one of our favourite stops.
The trail starts at a small parking lot located at this U-shaped bend on the Icefields Parkway (you can actually see the parking lot in the distance on the photo). It's a very short walk, but has a little steep section once you start climbing up the canyon.
Just be extra cautious as the trail gets slippery and falling into the canyon would be deadly.
