In reply to scottidog:
Higher Chelburn is not far from Blackstone Edge but only a 12min walk in and lots of easier stuff. Mostly fast drying. Loads of other great venues for low grade climbing on that moor - Stony Edge in particular, but mostly with longer walk ins. Not sure about 40min walk for Blackstone, seems like you'd have to be going pretty slow to do that.
Cadshaw small quarry is fast drying with lots of easier stuff.
Wilton 2 has a great slab and Wilton 3 has The Square, plus lots of other lower grades bits, but on Wednesdays shooters have priority.
Stronstrey Bank has some good fast drying easier stuff.
Healey Nab has some good stuff too, but probably not all as fast drying as Stronstrey.
Deeply Vale has a nice bay of easier bouldering.
There are others, but those are probably the most obvious. All in the new lancashire bouldering guidebook - details at www.lancashirebouldering.com
