Johnston Canyon hiking is one of the many popular things to do in Banff National park. Johnston Canyon is located about one hour and 45 minutes outside of Calgary. It's a spectacular drive in and of itself. Now I will say right off the bat here that this is not the most wheelchair accessible hiking trail I’ve seen, though it's not the worst either. The trail is clear with a mix of paved and dirt paths. The main issue is that is it often quite steep either up or down and can be wet. If you use a light manual wheelchair and have someone with you who doesn’t mind pushing you can probably do it. I went with family and we went for some distance but didn’t quite make it to the lower falls before we decided to turn back. Even on a warm day most of the trail is in shade so it's worth packing some warm clothing just incase.
If you do decide you’re up for the challenge though you’re in for a great hike. The trail winds its way through the canyon along the river. There are a number of nice spots to stop and take photos along there way and a bench here and there where you can rest. The distance from the parking lot to the lower falls is about 1 KM and the upper falls is about 2.7 KM. The trails continues from there if you’re either a fast walker or you just want to make a long day out of it. The parking lot has a decent wheelchair accessible washroom and wheelchair parking stops as well. Parking however can be an issue as the site is often very busy.
As Johnston Canyon is located in Banff National Park you must pay an entrance fee to the park. At the time of writing an adult day pass is $9.80 and a family pass for up to 7 people arriving in one car is $19.60 which seems like a pretty reasonable deal
