Aarhus sits on Aarhus Bay, offering a spread of sites that range from shallow harbour structures to a wreck resting at depth. The bay is cold year-round, warming modestly in late summer and dropping near freezing in winter, so a drysuit is standard. Sites include artificial reefs, a shallow wreck called Prammen, and mole structures such as Marselisborg Marina Mole, with depths spanning from a couple of metres to around forty. The port area has a dedicated diving platform to improve access for beginners and those with disabilities, and Kattegatcentret in the region offers certified divers the option to dive in a tropical shark tank. Marine life recorded here includes common lobster, monkfish, lumpfish, catshark, and harbour seal.
