The revamped play area at Sandringham Country Park has proved a hit with families.
Plans to extend and improve the facilities were revealed in the autumn and the first phase of the project is now complete.
Families have left rave reviews online, with an eight metre-tall replica Appleton Water Tower proving particularly popular.
The re-opening was delayed by the death of Prince Philip and the national period of mourning.
But the visitor centre, play area, cafes (takeaway only) and formal gardens are all welcoming visitors again. Car parking charges apply.
