It is still pretty warm in Gothenburg and it is hard to believe that it’s already the end of December and there is no snow. However, in order to experience some winter weather and to have lots of fun, you should visit Heden Ice Rink (Parkgatan 41, close to Kungsportsplatsen bus stop).
The rink is open every day from November till March, but for more specific open hours, please, visit: http://www.ispaheden.se/allmanheten.html
For students, cost of entrance and rental of skates is just 60 kr for the whole day, also it is possible to rent ice hockey equipement. Near the rink there is a small cafe, where you can enjoy some warm drinks and snacks.
