Passantenhaven Kessel is a visitor marina on the Maas, situated in the picturesque riverside village of Kessel, between Venlo and Roermond in the Netherlands.

It is operated by Watersportvereniging Poseidon and welcomes transient boaters to its association harbour. Berthing is permitted between 06:00 and 24:00.

Arriving visitors can take any berth displaying a green "VRIJ" sign without a reservation, then check in with the harbourmaster at the clubhouse "De Boei." Larger vessels of 13 metres or more are directed to the end pontoons.

A checkout time of 12:00 applies, and guests may stay a maximum of 10 nights. The marina sits close to the historic Kasteel de Keverberg and the charming village centre of Kessel, making it a scenic stop for those cruising the Maas.
