Atta Cave, Dripstone cave in Attendorn, Germany.

Atta Cave is a dripstone cave in Attendorn with 52 named chambers, including the Prophetenhalle and the Thronsaal der Fürstin Atta. Its show cave section is a roughly 500-metre circular route reached through a 90-metre gallery. The cave features numerous calc-sinter flowstone drapes coloured by iron oxides, plus stalactites, stalagmites and stalagnates.

Workers in a limestone quarry discovered the cave by chance in July 1907 during blasting operations. It opened to visitors that same year, making it an early tourist destination.

The cave's name comes from Princess Atta, a figure from local legend, and the 52 chambers bear fanciful names such as Prophetenhalle, Doppelgletscher, Thronsaal der Fürstin Atta, Sieben Zwerge and Eisbär. Visitors follow these named stations along the tour, and one section of the cave is used to store cheese sold as Atta-Käse.

The cave is located at Finnentroper Strasse 39 and maintains a constant temperature of around 9 degrees Celsius year-round. Wear warm clothing and sturdy shoes since the paths can be slippery.

The cave's 52 chambers carry fanciful names such as Prophetenhalle, Doppelgletscher, Thronsaal der Fürstin Atta, Sieben Zwerge and Eisbär. The name Atta refers to a princess of the Attendorner legend, after whom the throne room is named. The cave is owned by the heirs of quarry owner Eberhardt Epe.
