We spent a relaxing winter weekend in Sillico recently - a small hamlet of about 100 people in the region known as the Garfangana (just about a 2 hour drive from Florence). The Garfangana is up the Serchio river valley north of Lucca, and lies between the Alpi Apuane (famous for Carrara marble) and the Apennines. We stayed in a lovely little apartment that is part of a triplex just below (100 meters down the road) the town - there are two rental units, and the owners live in the third. You can find more about the house here (we highly recommend it!). There is also an excellent restaurant in Sillico, Belvedere, with regional cuisine, home made pastas, and a friendly and warm staff. We really enjoyed the dinner we had there, especially the copious antipasti (don't miss it if you get the chance) and local wine (€6 a bottle!).
The Garfangana in general is known for its chestnuts - and surrounding Sillico there are numerous marked walking trails through the forests and hills. Most of the pictures below are from the house and the walk we took in the immediate area. Sorry but I have yet to identify the names of the mountain peaks!
