There exists a list of ice reports covering lakes around the Täby municipality. Important disclaimer for the web: going on the ice is potentially dangerous, make sure you know what you are doing.
Ice on Rönningesjön
It is just appropriate to praise the public transport from time to time. Especially if it makes a trip to a frozen lake a breeze. This time it was Rönningesjön near Täby. The snow was cleared from a circular track on the lake that used to be a bathing place in summer.
