The town center, Piazza Mino da Fiesole, with its austere cathedral founded in 1028, is the starting-point for some exhilarating hill walks (the tourist office in the main piazza has walking maps), the most immediate being the steep paved lane leading from the square up to the small San Francesco convent and post-card views of Florence.
There are maps in the tourist office of Piazza Mino da Fiesole.
