We did this route on the 26/06/2020. We had sun, rain and fog but it is a nice walk.
The beginning is more of a guess till Coomataggart and even till Clognerargh.
Then there is a kind of a path, and from there you can follow the fence, you can follow it till Foilastooken or before starting to climb again, you should leave on your left and go straight till Conigar.
Once reached Conigar till Foilastooken is boogy and then there is a path to Gouganne Barra lake
