Just downstream from Grand Rapids Wilderness Adventures Cabins, on a isolated stretch of the Athabasca River, you can walk among some of Canada's, and possibly the world's, greatest examples of spheroid boulders. These massive concretions litter the river valley at this location by the thousands. These incredible natural formations are a geological wonder and a photographer's dream. Exposed by natural erosion from the sandstone banks in which they grew over millennia, they have come to form the awe-inspiring Class VI Grand Rapids.

Trips include river transportation, meals, log cabin accommodations a Helicopter sightseeing flight, with a set down and guided hike of this amazing, untouched slice of wilderness.
