Esteribar - Iruña-Frantzia (Aldude) / Pamplona-Francia (Alduides)

You get there by crossing the dam from the road. Turn left and there's a dead-end road. At the end of the road, it's a bit narrow, but I think you can get through. We slept very peacefully. At the very end, there's a flat area that can fit 4 or 5 campers.
