You can marvel at crabs, smelt, plaice, hermit crabs, mussels, snails, and sea scorpions (depending on the haul). Another highlight is the lock through the Eider Barrage, where five gates regulate the tidal state. National park rangers and guides, NABU employees, or the ship's crew will inform you about the region and the animals from the catch, and will gladly answer any questions. Plenty of free parking is available!
