I drove around the Banff Springs property on my honeymoon, but waited 6 years for my return trip before teeing it up. It definitely isn't mountain golf, as I walked both rounds. As others said, it is in a mountain setting. Moving back to the original routing would eliminate one of the all-time worst green to tee walks from 14 to 15, though it is a pleasant enough stroll.
I thought I'd add two additional perspectives of the Devil's Cauldron.
