We went there on 13 August 2015.
So does stinging nettle.
And the yellow flowers of narrow-leaved ragwort, originally from South Africa; present here for just over ten years.
On the sandy plain of the Zandmotor peninsula, scores of herring gulls and lesser black-backed gulls rest.
On some other days, one can see eg spoonbills and seals at the Zandmotor. We did not see them, as it was a busy Sunday. That dogs are allowed to run here without being on leashes probably disturbs wildlife.
Update, September 2016: here.
