Parker ridge was the third hike we did while in jasper but this trail is actually in Banff it’s just past the Columbia Ice fields. Anyone hiking in this area it’s a must see. The views are amazing from the top. It’s about 5km round trip and it’s a well worn trail. There’s switch backs but it’s a moderate hike. There’s a 250 meter elevation gain. The Saskatchewan glacier is in full view once you get to the top. You can either go down alone the ridge or up. Lots of little critters running around up there. If you want to beat the crowds early morning or evening would be the best time to go. Plus you’ll be the heat in the summer.
