Arrived last night in Limoges, France. The trip from Estremoz took me via Portalegre, Marvão, Caceres in Spain, Salamanca, Vallodolid, Burgos to Bilbão. Took about 8 hours. The road between Caceres and Salamanca is being upgraded to dual carriageway and once open should knock and hour of the route.
From Bilbao tried to get into France by off-motorway routes but the Basque towns are a menace as are the first towns in France Bayonne and Biarittz. I managed however to get through that and made my way cross country via Dax and Bergerac to Limoges.
Staying at a Balladins cheap and cheerful. Euros 28 per night with free wifi.
More in the next few days.
