In reply to Simon Caldwell:
We did find it, once we realised that the Norfolk Arms we were outside of (although within a couple of miles of Rivelin) wasn't the one on the Rockfax map and this wasn't the A57. Once on the 57, it was straightforward as we just looked out for a reservoir. The former Norfolk Arms on the 57 is now the Whitehouse care home.
First visit to crag and was quite impressed. Croton Oil best route I've done for a while. Altar Crack an experience to remember.
