If you've already been in Tuscany and want to see something new, try the
Maremma. I like both the coast (Populonia, the natural parks, the hill
towns of Bolgheri or Capalbio) and the inner part (Pitigliano, Sorano,
Sovana) full of Aetruscan tombs and memories.
The large villas in the outskirts of Lucca are pleasant, but I wasn't impressed by the town itself, except for the outer walls: too many cars around!
