One of the (tiny) forests in Flanders, the Hallerbos, is very well known for the bluebell carpet that covers the forest floor for a few weeks each spring. That "phenomenon" attracts tens of thousands of tourists over and over again.
And that is ... why I never visited it. If I'm taking photos of these flowers, I don't want people on them (not on the photo and not on the flowers). But - and I didn't know that - in a few of the forests in Wallonia, this "phenomenon" is growing too. We were lucky enough to walk right into one of those forests.
