In reply to MrRiley:
I've been and have never been so sandbagged in my life. There was a 4c with a move that wouldn't be out of place on a V3/4 j particularly remember. Essentially nice cruisy east route, stupid hard crux, run out to hell awkward corner to chains. Terrifying. Sailed up a 6c after that.
I also climbed some lovely routes and the rock is amazing but the grades make no sense.
The other gorge is equally amazing, but alas no climbing.
