We drove past last night, but it was late for my kids, and we have a tour booked with my Dad for later on this week so we didn't actually do more than just drive by.
Its pretty easy to get to, we came in on 12 Mile coulee and there was a sign at the first (or second) intersection and we just followed them in.
Stopped at the bottom of the hill and took a quick picture with my Playbook, but the quality isnt that great.
