1. easy access to water for the residents
2. in medieval times land transport was inefficient - the roads were usually poor, unpaved and carts could carry small quantities of goods. being located next to a river meant supplies could be transported by ships/boats - they carry more cargo more effectively.
3. protection - if one side of the castle was built along the bank of the river, approaching the castle from this direction would be difficult. The enemy must cross the river slowly in boats, while coming under fire from the soldiers in the castle.
It would be much easier to defend. It would be almost impossible for attackers to scale the cliffs and so the would be forced to attack from the other side. When this happens the defenders can be more focused on a smaller area.
They are less likely to be attacked there
