Possibly, but there's not enough detail visible for definite identification; could equally be a Picea species. Can you get a close-up photo of the foliage?
No, sorry, I tried to see cones to take a photo but there were none. I just got one more photo when I see the trees last weekend. I should have got a clearer photo of the foliage. The trees were in a natural place used to do experimental plantings of foreign species in the XIX-XX century. I thought they seemed to be a Pseudotsuga menziesii, that I read there are some big specimens in that place, but they would also be a Picea abies or an Abies alba as you said (there are specimens of that species too). Thanks anyway, Borja.
Did you notice if the needles were soft? Douglas firs also often have spent cones littering the ground beneath the trees.
Yes, I noticed the needles were soft to the tact. Surely there were cones on the ground but snow-covered, although I didn't even search too much. Retain Spruces or Abies alba their cones throughout the winter?
Mature cones of spruce might still be on the tree now, silver fir would probably only have the pegs on the branches left from the last season's crop - if that much. Most Abies bunch these up in a small area near the apex of the tree, although of those commonly cultivated where I live young Noble firs may have them spread out over the crown more, with some fairly low down. Large and pale when mature, these can look somewhat improbable when borne by smaller specimens.
