Parth pyramids:

The highest and most beautifully shaped earth pyramids in Europe can be found on the Ritten, and in three places at once: In the Finsterbachgraben on the way from Lengmoos to Maria Saal, in the Katzenbachgraben below Oberbozen and in the Gasterergraben in Unterinn. These bizarre formations, which rise from the earth, consist of cone-shaped heaped-up clay and boulders lying on top. You can reach the nearest earth pyramids in about 10 to 15 minutes by car or on foot in about 15 to 30 minutes.
