Four of us from California are wanted to set up a self guided tour of Tuscany on bikes for 3 or 4 days. We don't want to hire a tour guide or company for this - we want to do it ourselves. Are there established routes that are easy to discover or does anyone have suggestions on interesting routes through the region. We will start in one place and ride 40 to 50 miles and stay in another place and to the same for 4 days - not returning each night to the same place. Maybe we would consider a loop that would take 3 to 4 days.
