Büdös-pest, Cave system in Miskolc, Hungary.

Büdös-pest is a 37-metre-long inactive spring cave in Triassic limestone on the northern side of the Szeleta ridge, 307 metres above sea level and 42 metres above the floor of the Forrás valley. Its curved entrance measures 6.5 by 5 metres; inside, the passage is three to five metres wide and about three metres high, rising gradually toward a 7-metre-high shaft that opens to the surface.

The cave system formed in limestone and shows evidence of human presence from the Stone Age. Archaeological excavations have uncovered tools and remains from prehistoric times.

The cave lies in the Bükk National Park and has been fully protected since 1982; archaeological protection dates from 1951. Its name, "stinking pest", refers to the smell of the cave earth. Excavations here yielded a nearly complete Neolithic female skeleton, buried near the entrance with arms outstretched, aged 45–55.

The cave is freely accessible and needs no lamp, as daylight reaches the entrance. From the Majális park bus terminus in Miskolc, follow the red-cross trail past the Ampullagyár into the Forrás-völgy; after about a kilometre take the red-square branch up the side valley, then a narrow steep path marked with a red cave sign. The shaft at the far end is dangerous because of rockfall.

The cave is a 37-metre-long inactive spring cave in Triassic limestone, only 6.5 by 5 metres at its arched entrance. Inside, the passage rises gradually to a 7-metre-high shaft that broke through to the surface during excavation; approaching it is life-threatening because of falling rock. The cave needs no lamp to be seen.
