Fantastic, twisty road on the edge of the ocean. I did it south-westbound (starting at the French border). Mostly 2 seperate lanes, very well paved, double safety barriers. There is some traffic, some bikers/runners too. Views are moderate ... mostly forest or open paistries, but ... you get a splendid look at the ocean if you head up to the radio tower somewhere halfway (tiny road, a lot of sheep/horse droppings).
