Johnson Canyon is reservable and you will need to do this as it can get VERY busy in July/August.
Also beware the sites here are also near the railway and the Bow Valley Parkway.
If you want somewhere quieter (further away from the railway) go a bit further north to Castle Mountain CG, the disadvantage here is that it does not take reservations.
In case anyone is thinking about Johnston Canyon campground, here is a quote from the reservation site:
Due to ongoing construction to replace and upgrade underground services, Johnston Canyon Campground is not expected to open in 2019. Please check the Banff National Park Camping website for the most up to date information.
