In reply to Peakdistrict:
There are plenty of scrambles, safe mod and diff solos and boulder problems at Wharncliffe which I'd be a very regular visitor to if I lived 15 minutes from it (you are lucky as very few live that close as it takes nearly that long to get to the crag from the parking). We include much of the unlisted stuff on our Offwidth site (not all of which is included on the UKC databases Wharncliffe Crags ):

These need a Flash browser to view on a tablet or phone (eg Proton) but as an example of what we did there I copied a section for the Woods Upper Tier here:

A few old threads discussed this weird situation where there were more routes listed in 1900 than in 1989. For example:

Strictly speaking Wharncliffe isn't gritstone btw, it and quite a few other Peak sandstone crags are a different sandstone sedimentary form to gritstone, but are often bundled together and called gritstone for convenience.
Trad climbing in many areas of the UK has a special history, including its developed climbing ethics, and to protect that, that often includes a no bolting rule... this applies to all the sandstone crags in the gritstone areas. Anyone adding new bolts will find they will be quickly removed. There are very few exceptions... some old aid routes (where trusting the old bolts is brave) and a few climbs with inescapable tops with locally agreed very specific exceptions for bolted belays. Partly because of this, the 'I'm going to bolt gritsone' troll is a regular visitor to UKC and about as tedious as it gets. With your opening post most people here would just call troll. I'd prefer people just answer the questions, as huge numbers of new climbers wont even know 'boting gritstone' trolls are a thing (even though sneaky trolls will exploit this!
