How to get there
How to get to the lakeside promenade of Dongo by car: take the SS340 Regina State Road to Dongo and leave your car in one of the car parks located on either side of the road, in front of the lakeside promenade (you can also park in the car park in Via Amorati, behind the town hall).
You can also get to Dongo by bus, via the C10 Como-Menaggio-Colico line operated by the ASF Autolinee Bus Service (Paracchini stop) and by boat via the Navigazione Laghi-Lago di Como rapid services.

A pleasant walk along the side of Monte Bregagno at an average altitude of about 300 m, passing by the Church of S. Eufemia located in a panoramic position on Sasso di Musso and the hamlets of the municipalities of Musso, Pianello del Lario and Cremia before reaching the idyllic village of Rezzonico.

Route
From Piazza Paracchini turn left into Via Mercato and, at the underpass, turn right into Via 4 Novembre, then right again into Via Lamberzoni. When you reach the Romanesque church of S. Maria in Martinico, turn left onto the cobblestone path (marked “Church S. Eufemia/Vigero /Tegano”); at the three forks, take the left path and go up through the chestnut woods. At the end of the climb, the path becomes flat, then goes down to the Church of Sant’Eufemia (412 m), located on a ledge of the Sasso di Musso, which has a spectacular view of the surrounding area. From the church, go down a steep cobblestone ramp, and then continue down a flight of steps until you reach the hamlet of Genico. Continue along Via al Castello, turn right and go down some steps until you reach a small bridge. Cross the bridge and continue straight until you arrive at the Church of San Rocco. After crossing the bridge over the Musso Valley, walk through the town of Bresciana. Take a small path that crosses two small valleys until you reach a small parking lot. After a sharp bend, you will arrive at Coslìa (307 m), passing alongside the Church of Madonna della Neve. Head down towards the Valle Grande and cross the footbridge, climb up the path and take the mule track that winds down through the meadows. Take a flight of steps and then a quiet asphalt road to Camlago (282 m) in the Municipality of Pianello del Lario. Cross the small stone bridge over the Rio Campello and climb up a path, always keeping to the left, until you reach an asphalt road. Continue straight until you reach the hamlet of Cantone (319 m), then the hamlet of Vignola (335 m). Follow a narrow alley that crosses Semurano (349 m), exit through the portico and continue along a dirt track towards Valle Boggia. When you reach the hamlet of Cheis (345 m), walk down an asphalt road and cross an arched bridge over the Rio Vezzedo. Climb up a flight of steps to a small chapel in Vezzedo (327 m). A steep ramp begins here that descends amidst vineyards and fields and crosses yet another bridge, over the Valle delle Vacche.
Continue in the direction of Rezzonico, along the route of the Antica Via Regina and go around the Punta San Nicolao before reaching a votive shrine. Go down to the left across the steps.  
After crossing the Regina State Road (be careful) you arrive at Rezzonico, a few steps from the castle and the beautiful village, which is worth visiting.

Notes
Apart from the duration, the route is not very difficult, and there are only about three short steep climbs. To find your way around, it is advisable to follow the signs for the “Sentiero del Giubileo 2000”.
