A 10km walk around parts of the Geira Roman Road near to Terras de Bouro

There is a tourist office (portal) for the park at Campo de Geres which presents a number of shortish walks (Pequenas Rotas) of 10-20km.

I did "Pequena Rota 9" (leaflet with the route and information in English here) which covers an area to the south of the National Park proper around Terras de Bouro.  It actually covers in part a stage of the Geira Roman Road which ran from Braga to Astorga in Spain, and which is marked and preserved within the area of the park.

I started in the village of Chorense. Inexplicably - because there didn't seem to be a festival on - a speaker for a sanctuary on a hill above the village had been hijacked to play terrible Portuguese country pop music. This dominated the first 45 minutes of my walk.

 It's ok, a decent circular route which and it was nice to see the roman mile markers (each Roman mile on the route has roman mile markers still preserved).  The picture shows one marker at mile 16 showing the name of the Emperor Decio, I think from the year 250.

As with many of the tracks now within and outside the park, much of the route has been bulldozered, so it also serves for tractors and therefore off-road cyclists and motorbikers.  There is some nice oak woodland, though in many places the oaks have been supplanted by eucalyptus, presumably for commercial growing.

You're very much in the lower reaches of the hills and the villages you walk round are substantially modernised with less of the beautiful granite historic houses and farms visible that you see in the less developed, higher villages in the park.
