Jachthaven Rhoon is a modern tidal marina situated on the Oude Maas, near the southern boundary of Rotterdam, directly opposite the mouth of the Spui. It borders the Carnisse en Rhoonse Grienden, a rare freshwater tidal wetland considered unique in Europe.

The marina holds over 300 permanent berths and around 20 visitor berths, with floating docks and facilities including fuel (diesel and petrol), electricity, water, showers, and Wi-Fi. It carries the Blue Flag designation.

The surrounding area offers walking and cycling through the adjacent nature reserve, and a small ferry runs from the marina to Oud-Beijerland across the Spui.

Several restaurants, a pitch-and-putt course, and an adventure park are within close reach, and a metro connection to Rotterdam is accessible from nearby Rhoon station.
