Located not too far from the Sunwapta falls, Athabasca falls is a popular waterfall on the icefields parkway. At just half a mile round trip to the falls, it is great for a quick visit. Continuing upstream from the falls may give you a chance to separate from the crowds while seeing magnificent views of Mt Geraldine and surrounding peaks. There is also an area that lets you check out the slot canyon downstream, but it was still closed when I went there on May 4th. The falls itself was decent, but the whole area would be great for a picnic, which could pretty much be said for any stop along the parkway.
Athabasca falls rushing with Mount Kerkeslin in the background. The jagged nature of the rock here is because it is made of hard gog quartzite being sheared off as opposed to more smoothly eroded.
