Hi, on Sept 13 my husband and I will be traveling from Canmore along the Icefields Parkway to Jasper; from what we've read we'll be wowed all the way with spectacular scenery and lots of pulling off to drink in the vistas. We've decided not to do the bus tour out onto the Glacier, but we're considering doing one of two hikes--or part of one of them--if time permits: Wilcox Pass or Parker Ridge Trail. Problem is time--we don't want to be rushed, so can we hike along one of these trails for about a mile out for a good view? Any help will be appreciated. We're "older" hikers--mid-60s; husband has 2 knee-replacements so not-too-strenuous is best--I've read that Parker Ridge is a gentler hike. True? Many thanks! Can;t wait for this trip!
