Rhoon is a village that borders the municipality of the city of Rotterdam, South Holland, the Netherlands.
This is a large protection barrier of dikes and dams to keep the water of the North Sea out during high tides.
In 1969 Rhoon also became part of this plan and a large dike was established around the island of IJsselmonde.
On the lands outside the dikes is a small yacht marina on the banks of the river Oude Maas, and also a "griend" which is a tidal forest.
The river Oude Maas has a tidal difference of around 1.2 meter in a twice daily cycle.
