Flanders Today just ran a 4 part series on some nice winter walks. If you have not subcribed I would recommend you get this free English weekly. A good mix of Flanders news and tips on what to see or do.
If the weather turns wet and cold again go see the Frida Kahlo art exhibit at the Bozar museum in Brussels. A hard life turned into beautiful paintings. Not recommended for children given the subject matters of some paintings.
When: until Sunday 18th April
