From Balneario Lobios-Caldaria, this route starts heading north towards Alto de Santa Eufemia. After leaving the area of Río Caldo and traveling a few meters along the OU-312, we turn towards Bubaces and Padrendo, where you can visit the chapel of Santa Catarina and observe the uniqueness of a dovecote. Leaving Padrendo behind, we continue the route that leads us to Chan de Ventoselo by an ascending track in very good condition that allows us to enjoy a spectacular panoramic view where the Corga da Fecha stands out in the background.

For those who want to do a simpler version, halfway up the ascent there is a signposted detour on the left hand side that goes towards Torneiros and allows you to return along a very easy track to the Lobios Caldaria Spa. Those who opt for the long version of the route, will continue the ascent until reaching a detour to the right towards the Alto de Santa Eufemia from where you can see part of the extension of the Natural Park Baixa Limia-Serra do Xurés. For reasons of preservation of the natural environment in which we are, the 2.5 kilometers that separate the main track of the high, have to be done carrying our bicycle.

From this point, the route continues towards the border with Portugal and turns to the left to connect with Route 6 "Via Nova" where we can visit a set of milestones (ancient system of milestones of the Roman era represented by stone cairns), turn off to the Corga da Fecha or visit the remains of a Roman mansion used as a thermal space and known as Aquis Originis, before returning to the spa.
