In February the natural ice skating rinks are in the best condition. Since this winter 2012 has not been good for tour skating on lakes and the sea, it is a good option to go skating on maintained skating rinks.
In Helsinki and Espoo in southern Finland there are tens of well maintained rinks. See status of rinks of Helsinki and Espoo (updated in Jan.2014). See webpages of towns and municipalities all over Finland of their listings.
