I went there for an afternoon a few years back when visiting the Falls, got on the tourist bus to the glen. didn't have a mat but found enough to do, some nice variety of stuff, HVS-ish highball walls, low roofs etc. can't remember what that sector was called, it was the main one. Loads of stuff there, would be good to get a tour with a loacl. I thought it was good but probably not worth a 7 hour drive on its own. If you're visiting the falls though its worth checking out, or if you're in toronto you can make a day/s out of it, and is in a nice spot away from the main tourist trap of the falls. I did have a couple of photos of it on the old UKB gallery, don't know where they ended up.
