Next up on the itinerary, Amstelpark. On the outskirts of the city, but totally worth it. The park includes mini golf, inappropriately called Midgetgolf, a few play structures, a train, a city farm, snack bars, and a small amusement park with rides perfect for young riders.
On a rainy day, NEMO science center is a great option. With four stories it provides a full day of entertainment. It was more appropriate for Bijou at 8-years-old but Eero and Wilder were entertained by the endless button pushing opportunities.
