1) Is the train journey scenic over the mountains?
2) Is there anywhere safe and secure to leave our vehicle with our luggage overnight at the station in either Oviedo or Gijon?
3) Is there anything in particular that is a must for children in Leon?
4) Is this 2 day/1 night trip worth the effort? or is there 'an equivalent' along the coast? bearing in mind we will have been walking in the picos for a few days already.
I would be grateful for any advice!
