"You can go to Puerto de Navacerrada for a few hours of skiing then return to Madrid to continue visiting the many attractions in Europe’s fourth-largest city."

In Madrid (region), at less than an hour driving, we have a Sierra where we used to have 3 skiing stations. Now we only have 2 (Navacerrada and Valdesquí) because Cotos had to close. And snow melts more quickly. My father always boasts that he once skied in the Madrid Sierra on May 15th, and with current climate that's difficult to believe. But I've seen how the skiing season gets shorter year after year. 15 years ago everybody made plans for going skiing to the Pyrenees on the Inmaculada holiday (early November), and currently all bets are off even for the Constitution holiday (early December).
