When the negative temperatures stay long enough for the canals to freeze, the Dutch (and all other ice-skating lovers) start counting the days and the ice depth! This year we were lucky to have the cold and minus 16 to minus 7 (around the Hague, more in the rest of the country) over night for almost a week now and the natural ice skating rings got ready!
Ice-skating on frozen canals is something like national sport here. The people first clean the canals from the snow and then everyone gets on: with skates, shoes, sleights or something else! l do love it too, so today I enjoyed a sunny day ice-skating with some local colleagues!
One may skate on frozen canals or lakes or go to some official "ijsbanen" such as the frozen lake in Schipluiden, see last 2 pictures from sunny skating in club "Vlietland" before/by sunset there last Saturday!
