Located in the municipality of Halle, about 30 minutes south of Brussels, lies the forest of Hallerbos or Halle's Wood (English). Hallerbos is covered by a splendid carpet of wild bluebell hyacinths. Bluebells have a delicate scent of green leaves, cloves and lemony roses, but when all of the flowers burst into bloom, the fragrance in the air is rich and heady. Access is free of charge, and in exchange, visitors simply have to abide by the rules-not to wander off the marked paths and not to pick flowers.
