The route after Presedo goes well away from Bar Julia. There is still a hill up to Hospital de Bruma, but it is an hour's gradual climb through forest roads, as opposed to a slog.
I did not see markers for the old route after Presedo, but I did meet one person at Hospital de Bruma who had walked along the old route, thereby meaning that it is possible to walk the old route, provided that you know where to turn off.
Whilst on the subject of old routes, I ended up walking the old route to Cabanas from Vilar de Colo, because there was a lack of waymarks on the roundabouts under the motorway, and was directed on the old route by a friendly local. There were no official markers left, but at each 'junction', there was still sufficient yellow arrows painted on streetlamps, walls or the road, enabling me to reach the beach at Cabanas without too many problems. The old path from Presedo to Hospital de Bruma is more in the countryside, and therefore, it would be interesting to hear from anyone who has walked this after the official reroute to hear how well marked the old path to Hospital de Bruma is? Although the new route takes the big hill out, walking for 30 minutes on the main AS-542 road alongside a large electricity substation was not too much fun, and I was not impressed with Bar Avelina that you pass there.
