Shrimp fishermen on horseback + shrimp cooking
Beach at Astridplein, Oostduinkerke-Bad
Unconfirmed. The official horseback shrimp-fishing calendar lists no session on 22 August 2026; its August dates are 15 and 17 August, then 30 August. What does run at this hour on 22 August is the on-foot demonstration by the women's shrimp-pushing group De Stienesteekers, 14:45 to 16:15, which this planner already lists separately. Treat this entry as doubtful until the town confirms it.
