Ten minutes from the town of Canmore, Grotto Canyon can only be accessed on foot. Take the trail from the Grotto Mountain daytime car park and walk about a kilometre to get to the narrow-walled creek bed, which twists for another kilometre. As the smooth limestone walls get steeper, you’ll come upon a fork in the creekbed. Heading right takes you to a glistening waterfall. If you look carefully, just before the falls on the left at eye level, you will see Hopi pictographs, painted some 500-1,000 years ago. Walk it in summer or go with a guide in winter.
