Nesso is on the Como "leg" of the lake, along the road from Como to Bellagio. It is an old centre with picturesque groups of houses, spread along the hilly slopes and along the shore of the lake. The village centre is situated in the point where the Tuf and Nosè streams, which descend the Pian del Tivano, join and form a waterfall that plunges spectacularly into a gorge. This can be seen from the road or from the lake, by passing under an old bridge in a boat. Nearby, there are the ruins of a castle with a high wall and three small towers. The Pian di Nesso (Plain of Nesso) is at a height of about 900 m. It is a scenic mountain locality and is on the way to Monte Palanzone and Monte San Primo.

The Church of San Martino, in Careno
This small church is probably from the second half of the 12th century. It has one nave and the entrance to the portico has a mullioned window with two lights. A square apse was added at a later time. There is a tall bell tower attached to the facade. It was raised during the following centuries and has a level of mullioned windows with one and two openings. It is worth noting that Careno is one of the prettiest villages on the lake.
