Moerdijk is a town situated on the southern bank of the Zuid Hollandsch Diep, where the Dordtsche Kil connects to the broader waterway system.

The area sits within a significant river network formed by the confluence of the Bergse Maas and Nieuwe Merwede, which together shape the Hollands Diep — an estuary of the Rhine and Meuse rivers.

The Moerdijk bridges span the Hollands Diep on its eastern side, providing key connectivity across this wide waterway.

The surrounding region offers access to expansive open water, making it a notable point of entry for those exploring the Hollands Diep by boat or on foot along its banks.
