Hi!
My Name is Enid. I currently live in Arnhem, but I grew up in Aruba.
According to Stadsbosbeheer, it is legal to forage in Arnhem. There are some rules to it though: https://www.staatsbosbeheer.nl/contact/toegangsregels/wildplukken
I haven’t heard of people getting in trouble for foraging here yet.
In Aruba, you are allowed to forage whatever you’d like.
