While the era where happy Dutch people go ice skating on the frozen canals of Amsterdam may be over, you can still find ice skating around town.
Yesterday unfortunately they packed up the ice skating ring at Leidseplein, but until March you can rent some skates and get on the ice at Museumplein. Also if you find yourself exploring the North of Amsterdam, there is an ice rink for another 5 days at the Buikslotermeerplein.
Clearly your best bet is the museumplein rink, which will be in service until March. I like going by just to snap pictures of parents helping their children use wooden chairs to keep them balanced.
Skate rental is somewhere around 3 euros I believe. Bring an extra euro or 2 just in case, especially for some hot chocolate afterwards.
