heck of day. I got up 5am drove 3 hours out to Cadamin, Hiked 2miles up the side of mountian and then into a cave. the cave itself is about 2 miles long, and drops about 700 feet over that distance, but I only went into it about 1/2 way and then headded back. the round trip on the hike took about 6 hours.. I would call it a difficult and strenuous day hike. one of girls with us got so scared at one point she was in tears, she freeked out climbing up the side of the mountin. 3 of thoes hours where spent inside the cave. it verry slowgoing in their, its cold,its hard to see, its slippery, and plenty of littel holes and things stick a leg into, slip trip fall on/in etc. several spots where you need to rope up too, its about an 80 foot vertical drop into one of the lower caverns anywasy its been a long day im beat, Cadomin cave alberta the 2 km long trail climbs 300m (984f). the cave etrance elvation 1891m (6200f), Length 2791m (1.7miles), Depth 220m (721f) if you want photos googgle "Cadomin cave"
