This is a circuit taking in the most interesting religious buildings of the central section of the Comunità Montana della Montagna Fiorentina.

Starting points
Any point along the circuit can be chosen as a good starting point. Most cyclists may prefer to start from Rufina and enjoy the downhill roads on the way back.
From Rufina, head north following the congested main road (S.S. 67), leaving it after just two kilometres to take – to your right – a scenic road climbing up the hillside of Castiglioni, among beautiful olive groves. On the other side of the valley, is the cold eastern side of Monte Giovi, covered with thick woodland.

From Castiglioni to Pomino
Even if the road uphill is hard for cyclists, the toughest part of the ascent is represented by the hairpin bends during the first kilometres or so. Past them, the road proceeds uphill for a couple of kilometres to meet the Pieve di S. Stefano at Castiglioni, a remarkable Romanesque building overlooking the valley from a dominant position. Below, on a cliff, is the castle of Castiglioni, a feudal estate belonging to the Bishops of Fiesole. The ascent is gentler and gentler until it gets to the valley of Pomino. The first stop, near Villa Petrognano, is to visit the homonymous church, dedicated to St. Peter.
Follow now the main road, almost flat, along the sunny side of the mountain: below, is Villa delle Lame and the vineyards producing the grapes of the famous Pomino label.

One final stretch uphill and you get to Pomino. To the left a short detour takes you to the Pieve di Pomino, one of the most interesting examples of Romanesque art in our area, which houses interesting works of art.

Towards the church of Tosina
The circuit proceeds along the same road, passing by Villa del Palagio and reaching, after two kilometres, the mill at Mentone. Here begins another uphill stretch, but you can soon stop to visit the church of S. Margherita at Tosina, which is built on a terraced field overlooking the valley.
The road uphill continues for one more kilometre, until you meet a main road (S.S. 70) at the old tavern at Borselli. From here a quick descent towards Diacceto where, at a fork, the left road leads to Pelago and the right one to Falgano.

The Falgano Valley
Past Diacceto, turn right towards Falgano, through fields and open land, to meet the palace of Poggio al Commissario, dating back to the 15th century and now converted into a rural building. At Falgano there are two churches: S. Giusto and S. Maria, in Romanesque style. The final part of the circuit is along a road halfway up the hill leading to Casi – a built-up area of just a few houses on the ridge separating the valleys of Falgano and Pomino. The landscape is suggestive: you’re in the middle of the countryside. Now an easy descent leads back to Rufina.
