Jachthaven Katwijk is a welcoming, sustainably operated marina situated in the estuary of the Oude Rijn, approximately 950 metres from the North Sea beach — billing itself as the only marina on the beach in Noord- and Zuid-Holland.

It accommodates around 274 permanent berth holders and up to 130 visiting boats. Berth boxes range from 5 to nearly 14 metres in length, while moorings on the north side of the Oude Rijn can handle vessels up to 17 metres.

The marina holds Blue Flag and Green Pennant certification (2025) and is set among the Zuid-Hollandse dunes, within a short walk of the centre of Katwijk aan Zee with its shops, restaurants, and beach boulevard.
