Rio Molino is a marina (jachthaven) situated on the Rottemeren in the Netherlands, close to the town of Bleiswijk. It serves as a practical access point to the waterways of the Rotte, offering both boat rental and mooring berths for private vessels.

Berths are reached via wooden jetties and are in high demand given the area's popularity. From Rio Molino, boaters can head out onto the Rottemeren for relaxed recreation or navigate further afield toward Rotterdam or Delft.

The marina's location near major roads and the built-up area of Bleiswijk means it is possible to move quickly between the heart of the Randstad and one of the more tranquil stretches of water in the Netherlands.
