Halverwege is a tidal Oosterschelde dive between the Zeeland Bridge and Kulkenol, with a calmest window at slack water and the option to let the current carry you toward the bridge. The site is a quiet, biodiversity-rich stretch of hard bottom and bridge-edge structure that attracts cuttlefish, squid, seahorses, and other cold-water life. It is best for divers who are comfortable reading the tide and planning the entry around current.
