Advice for Wales in September

Hi I am going for a weeks laning in Wales in September rough camping so should be fun!! Can anyone recommend good areas or lanes that shouldn't be missed?? Any help greatly appreciated

Ok having read a bit further I realise nobody is going to post up grid references and things like that! personally I am a responsible user of the lanes and like the fact that you guys don't give out this information to any fool so they can go and rip up the country side.

can anyone recommend good/favourite areas within wales?? I have done quite a few trips in the Hay on Wye area and would like a bit of a change.

Cheers

Personally I only know around the Bala / Machynlleth area. I suppose it depends which end of the country you're coming from. Plenty of lanes on trailwise......
