This route leaves Trancoso from the south side, goes into a dirt road and descends towards Miguel Choco. From there, and passing soon afterwards through Venda do Cepo, it catches the beginning of the Muxagata stream. It goes down the initially narrow valley of the stream and follows this water line through Aldeia Nova, before reaching Muxagata. From this village it goes south, following the stream of the same name to its mouth, on the Mondego river. In this river it is necessary to cross a dam (conditioned crossing in flood period, see alternative). Leaving the valley, in latter one  crosses the EN16 and reaches Vila Soeiro do Chão. Using mostly dirt roads, it passes through Mesquitela and Carrapichana. In the latter, it crosses the EN17 and continues south, gradually rising until reaching Figueiró da Serra, where it descends to the Linhares stream and converges with the PR4, going up the Roman stone road to the historical village of Linhares da Beira.
