We were there yesterday... gorgeous, amazing, gobsmacking!....
We crossed La Quesera without a problem (there wasn't too much snow) but after having lunch in Riaza, Segovia we went back to Wadi-al-Hajara and drove like 70 miles of beautiful snowy tracks... we ended up on a hill near Cantalojas, beaten by a powerful snow drift while the night fell upon us... we lost the track within so much snow and it took us 3 hours to find our way down the very steep banks of the hill to Cantalojas....
