In reply to PhilMW:
The old guide, though cool, isn’t very good for Helman - not good at all in fact.
Far better to get the more recent Cheesewring guide which is excellent generally and comprehensive for Helman.
Boulder Britain is just as good for a casual visit up to about 6C+
Either way, most of the better problems are fairly obvious and can easily be navigated by using the UKC page.
Hope that helps.
Cheers,
Tom
