Brussels may be a busy town, but the tourists, real or virtual, can find numerous spots of greenery for a quiet stroll -- whenever the weather permits. The Cinquantenaire Park offers its lawns and avenues to joggers, dog owners, families and civil servants from the nearby EU headquarters who need a breath of air between meetings. The park hosts several museums as well as the Brussels Mosque. On summer evenings, various ethnic groups will gather here to practise their favourite sports.
