In September 2021, I completed the last hike from the booklet Green Heart trails of the ANWB. This booklet contains 43 round trails in the Green Heart region in the Netherlands. The booklet is no longer for sale and the hexagonal ANWB trail markings are outdated or no longer present everywhere, but the trails can still be hiked and found here and there on the internet. Therefore, I created an overview of where you can find these trails online. I also describe a top 5 of favourite hiking trails from this booklet.
