I've just heard that there is a spring fair in Nabuel from 20th April until 6th May. It is in its 45th year and sounds good fun. Apart from all the usual stalls etc. there is a funfair for the children, entertainers, cafes, foodstalls etc. If anyone is in the area then it is in Avenue Habib Bourguiba and if you just follow the crowds you can't miss it.
