Yep, there are loads and I know you gave CaptainFlashheart a hard time but it's worth picking a base and getting some maps packing a bag and just head off for the day.
I can leave my front door (of the house in Wales) and within minutes be up on the hills.
I have a route which takes me out accross the hills and over up to Cadair Idris and back. There's technical stuff, downhill stuff, climbs, fords to cross.
I'll see if I can draw it up.
But you can't go far wrong if you pick a good base maybe Brecons or Snowdonia get out a map follow it 50% and follow your nose 50%
