Exploring the grounds
The estate is open free of charge every day within the applicable opening hours. So you can come for an outdoor visit without automatically booking a castle tour. Do check whether an event is temporarily affecting access.
Inside with a guided tour
For the castle itself, you book a guided tour. It lasts about an hour and a half and is in Dutch. It is not suitable for children under ten. Available days may vary, so follow the current booking calendar.
Keeping three names apart
Kasteel Keukenhof, the estate and the flower park are not the same visit. Check the correct address and your chosen activity before you set off. Restaurant De Hofboerderij also has its own opening hours; access to the grounds does not guarantee that you can get in there.
Before you go
Check the current opening hours of the grounds and the available guided tours. Parking with a motorhome or caravan is not possible.
