The sign says: These dunes are natural habitat and they protect the land against the sea. Trespassing causes damage!
Further more it states the Criminal Law Act 461.
This law counts for all of the dunes along the Dutch coast. So better be well aware not to venture outside paths when warnings like these are up. I must also add that I hardly ever, if at all, see people ignoring the warning.
The sign clearly states what is and isn't allowed on the beach.
The red word 'Verboden' means 'Prohibited'.
The icons with the * are prohibited between 15 May and 15 September between 10-19 hrs.
Surfing * (except when there's the sing with the 3 blue lines)
Swimming at your own risk
Water quality and safety are periodically checked.
To protect nature and sea defense, it is prohibited to enter the dunes, also from the beach!
Other tel. numbers:
Alarm number 112
Police: 0900 8844
There is a Dutch saying: You can walk on the heads.
At times that certainly is true for the popular main street where it seems all traffic wants to pass at the same moment (including two public transportation buses per hour).
It's a busy mix of walker, cyclist, cars and who knows what that squeezes its way through the narrow streets.
