The best time to visit Johnston Canyon for most travellers is during late spring (May to early June) and early autumn (September to early October).Late spring offers the advantage of melting ice and snow, which means the waterfalls are at their most powerful, creating a truly impressive display. The weather is generally mild, and the trails are typically clear, making for comfortable hiking conditions. You'll also find fewer crowds compared to the peak summer months, allowing for a more relaxed experience.Early autumn is another excellent choice, as the larch trees in the surrounding mountains begin to turn golden, providing a stunning backdrop to the canyon's natural beauty. The weather remains pleasant for hiking, and the summer crowds have thinned out, offering a peaceful visit. The air is crisp, and the photographic opportunities are exceptional during this season.While summer (July and August) is popular, it's also the busiest time, which can mean crowded trails and parking lots.
