Altenburg Aquarium is an advanced freshwater dive site on the Rhine River near the Swiss-German border. This Rhine dive takes place near the ruins of Altenburg castle, where the riverbed features interesting rock formations and deeper pools that create a natural aquarium effect. The current can be moderate to strong, justifying the advanced rating. The river supports trout, barbel, chub, and pike, with crayfish in the rocky areas. Visibility depends on river conditions but can be surprisingly good during low-water periods. The combination of historical setting, challenging current, and diverse freshwater life makes Altenburg Aquarium a unique and rewarding dive for experienced river divers in the Upper Rhine region.
