On 20 September, Bunker-Doe-Dag sends families on a 3.5 km route through Midden-Herenduin, with bunkers, trenches and a tank ditch; starts run from 10:00 to 13:30.

What you need to know

Children do not stand before a display case memorising dates. With a backpack and map, they consider where a soldier could shelter and why concrete was camouflaged. Walking and searching make history tangible, while adults still need to separate adventure play from the real weight of war. The activity is recommended from age six and must be finished before 15:00. Children cost €5, or €2.50 for members, with tickets sold on site that day. Natural terrain makes 3.5 kilometres harder than a city walk, and Natuurmonumenten explicitly advises a tick check afterwards.
