Its source is on Pizzo del Lago, at an elevation of {{convert|3050|m|ft}}, on the north side of the Val Bregaglia and close to the Swiss border which here marks the limit of the Po drainage basin. From here it flows in a southwesterly direction within the territory of the commune of Piuro until it joins the Mera as a right tributary at the locality of Borgonuovo, a little upstream from Chiavenna and the mouth of the Val Bregaglia.
At an early point of its course the stream forms the lake of Acqua Fraggia at an elevation of {{convert|2043|m|ft}}; it then runs through two hanging valleys of glacial origins, emerging from each in a series of waterfalls, which were noted by Leonardo da Vinci in the Codex Atlanticus. This has been a protected area since 1983. <gallery> File:Cascade Acquafraggia 2015 07 - with surroundings.jpg|Waterfall called Cascade Acquafraggia. From 2015-07.
