Ronco s/Ascona extends from Porto Ronco at about 200 metres to the height of 1300 metres in the mountains. The picturesque, quaint-looking centre rests on a prominence in the mountain side at a height of 350 metres. Three main horizontal roads connect the tortuous, vertical paths. Ronco has always been an artists' village; Antonio Ciseri painted the altar picture in S. Martino church in 1870 where 15th-century frescoes depicting the four seasons can be admired.

The German writer Remarque chose the shores of Porto Ronco as his favourite residence. A mild climate and spectacular scenery invite the nature-lover to visit this remarkable corner of Lake Maggiore.
