Key Dive Site Facts
Dive Site Overview
Diving at Zeelandbrug offers an exploration of the underwater structures beneath the long bridge. Divers typically enter from one of the designated stairs, allowing direct access to the water.
This provides a direct path to the abundant marine life populating the submerged environment. The dive site primarily consists of the bridge pillars themselves, the adjacent dike, and a rubble stone reef, all of which are richly overgrown with diverse marine organisms.
At its deepest, this site descends to about 21 meters, though many points of interest are found in shallower sections, often just a few meters down where light penetration is greater. These varied depths cater to different experience levels.
In 2009, steel slag was used to reinforce the dike, which initially impacted local marine life; however, the ecosystem has since recovered, providing renewed interest and demonstrating ecological resilience. Experienced divers have the option for drift dives from Zeelandbrug to adjacent sites like Halverwege and De Val, extending their exploration beyond the immediate bridge area and discovering broader patterns of marine life within the Oosterschelde.
