Rearguard Falls Provincial Park is a scenic gem just off of the Yellowhead Highway. We discovered it by accident as we were driving along Highway 16, near a small town called Tete Jaune Cache in British Columbia, Canada (not far from Valemount, BC). This scenic jewel has a viewing platform for a stunning view of the waterfalls. During the fall, you can even watch the salmon run, if you're lucky!
The hiking trail itself isn't very long nor is it strenuous. It's about a 1/2 hour return trip although you will want to leave extra time to enjoy the view. It is a lovely little walk and worth a visit.
Rearguard Falls Provincial Park is located near the Alberta/BC border, near the headwaters of the mighty Fraser River. It's about 6 kilometers east of Tete Jaune Cache, BC along the Yellowhead Highway (Highway 16) and just down the road from Mount Robson. Valemount, BC is the closest "large(-ish)" town with full tourist services.
