The hamlet on a promontory at the confluence of the Isorno and Melezza rivers.
The Melezzo Orientale (known in the Swiss part of its course as the Melezza), a tributary of the Maggia which flows eastwards through the Val Vigezzo in Italy and the Centovalli in Switzerland
To begin with the river runs south forming the deep valley of Arvogno (a locality within the commune of Toceno); near Santa Maria Maggiore (VB) the course turns east and takes it through the gentler slopes of the high plain which forms the central section of the Val Vigezzo; at Malesco it is joined by the Loana.
