In reply to Charlie Fells 1994:
Harlow not bad for routes. Tends towards vertical to slightly overhanging, nothing particularly slabby. Lots of corners if you like bridging!
Bouldering is extremely limited. There is a small bouldering 'attic', although problems are only perhaps 3m high and there aren't many of them.
Worth a visit if you plan to climb routes, but not if you're planning to boulder/going alone (no auto belays last time I went)
