(47100) Tordesillas - Carretera de Burgos a Portugal por Salamanca

Lovely space just a bit off the highway with a view of the Duero. There are two entrances, one is near the exit and another down the road. When coming from exit 157 going south, take the second entry if you don't have a 4x4 vehicle (you should see a stop sign). Swimming doesn't look very tempting and you have some road noise, but it still seems like an ok place to spend the night.
