I walked the Camino Primitivo in June/July this year. Between A Mesa and Grandas de Salime there was a signpost pointing to a "temporary" diversion. There was nobody about to ask (and no reason to expect that anybody would know any more than I did whether or not to take the diversion) so I followed the sign. After about three hours I met up with the original route and several people who had been advised by the manager of the hotel they had stayed at to ignore the sign. The diversion, I was told, added 4 km to the journey and was because there had been a forest fire FOUR YEARS AGO! If you are walking this route in the future, please save others from this unnecessary diversion by removing the sign.
