This walk goes through the beautiful valley of the Aa towards the old hamlet of Sassenhout. From there you walk through mixed forest and an open field and meadow landscape in the direction of the old agricultural hamlet of Berkelheide. Along the Bosbeek and the hamlet of Vispluk you arrive at the impressive castle of Vorselaar, the Borrekens. You walk back to the starting point through stately beech avenues from the castle grounds.
