The Erdmannshöhle (Dwarf Cave) is a pretty unique sight. Although it is promoted to be a dripstone cave and all descriptions emphasize on formations and - of course - dwarfs, there is much more. First it is one of only two show caves in the remote southeastern corner of Germany, located in an isolated patch of limestone with several caves. Then it has a very long and interesting history, with vistits of margraves and grand dutchesses, early scientific publications and mystic legends.

The Dinkelberg at the southern rim of the Schwarzwald (Black Forest) is a small limestone area built of rocks from the Muschelkalk or Middle Triassic. During the uplift of the Black Forest, the rocks on the southern edge were also uplifted, but by a much smaller amount. As a result, the limestones that lie deep underground further south, and in the Black Forest itself were uplifted to such an extent that they have now been completely eroded by weathering, lie exactly on the surface in this "intermediate stage". A subsection of this area, defined by the catchment area of the Hasel river, is called Haseler Karst. The heavy karstification is a result of the big height difference to the drainage, the Rhine river, and the disruption of the limestone by the intensive tectonic forces. The surface is covered with karst features, dry valleys, dolines, karren, and a karst lake. The area has a size of only seven square kilometers.

The Erdmannshöhle is an important drain of this area. The cave has two different levels. The upper one was formed less than 100,000 years ago and is now dry. The lower level is still active, with a nice cave river, and was formed during the Riß-Würm-Interglazial.

The cave is located at the lower end of the small village Hasel. Follow the signs from the highway, turnoff to Hasel, in the village at the church turn sharp right. A narrow road leads to the city limits and finally, at the end of the road, behind the fire department, the parking lot of the cave is reached. The entrance, once only a gap in the rocks, is today covered by a small building housing a small shop, the ticket office and an exhibition.
