The Arnica Lake trail is a challenging but rewarding hike that takes you past Vista Lake before ascending through lush forest with beautiful valley views along the way. At 10 km round trip, this trail offers a steady climb, making it a great choice for strong intermediate hikers.

In autumn, Arnica Lake is especially spectacular, as the surrounding larch trees turn brilliant gold, creating one of the most stunning fall hikes in Banff. Whether you’re visiting for the crystal-clear alpine waters or the vibrant fall colors, Arnica Lake is a breathtaking destination worth the effort.
