Est-ce que les magasins à Katwijk sont ouverts le dimanche?

[Réponse en anglais]

No, Katwijk has no Sunday shopping. All shops in Katwijk are closed on Sundays. Only restaurants and cafes are open during Sundays.

The upcoming local shopping opening hours à Katwijk during Sundays and public holidays (like Easter, Pentecost, Christmas, etc.), can be found at the following website: http://koopzondagen.net/#Zuid-Holland
