Esoteric, and almost a gem, given more traffic to clean up the routes. Shrouded in trees, the cracks can be slow to dry but the more open climbs are surprisingly fast drying, and of course avoid the worst of the weather over the higher Peak edges. Best on windy days in Autumn and Spring when the leaves are off the trees. The path above and below the crag is improving and it is worth nipping over from the main crag to pick off a couple of the more popular routes which generally stay clean.
Recent developments have added to many worthwhile climbs here, but most of the quality lies in the extreme grades. Best routes are Impecacuanha Groove (HVS), Rhododendron Crack (E1), The Two Toms (E1), Portnoy's Complaint (E2 5b), Paddington (E4) Teddy Bear's Picnic (E4 6b), Feet Neet (E5), Flex (E5/6) and Earthboots (E6/7). The blank arete of That's My Lot (E8) is worth looking at and wondering how it is possible!
There is also worthwhile bouldering here. The Mini Beak and Happy Campus area is popular and accessible from the main crag, while a scattering of other problems further along the quarries are also worthwhile - Glom Onto (7A), Geisterspeil (7A) and Cold School Closure (7B/+) in particular.
Most will approach by traversing left from the left-hand end of Rivelin Edge, either on the path above the edge, or below. The first quarry is reached in a few mins.
Please be respectful of the residents of the nearby houses if climbing at the far left end of the crag.
