Explore underground on this caving trip to Rat's Nest Cave located under Grotto Mountain near Canmore, Alberta. This wild undeveloped cave has no artificial lights, boardwalks or handrails, it is a cave in its natural state. Discover how caves form; find out how animals and humans use caves; examine stalactites, stalagmites, animal bones and fossils; learn about the geology of the picturesque Bow Valley in the Canadian Rockies.
More than one ton per second of water was pumped through this limestone cave system from extinct glaciers of the last million years. As you walk up to the cave you will look down on the Bow River as it flows along the huge glacial valley that once contained the cave-forming glaciers. Now the glacial waters have drained from the cave leaving glacial deposits, and glistening calcite formations, all of which you can view in perfect safety.
The adventure begins in Canmore with a 10 minute drive to the base of Grotto Mountain followed by a 30 minute hike to the cave, through a scenic montane forest. The longer tour includes a short rappel in the cave. Expert guides take you on a Natural History tour of this exciting underground world - etched and sculptured over hundreds of thousands of years - through twisting passages and chambers of stalactites & stalagmites, animal bones and fossils.
