Tétényi Plateau, Protected nature area in Pest County, Hungary

The Tétényi Plateau is a limestone-capped geographical small region south of the Buda Hills, rising to 267 m at Anna-hegy in Törökbálint and 227 m at Vadász-hegy in Kamaraerdő. Its surface is broken every 600–800 m by 5–10 m steps, and the Égett-völgy between Törökbálint and Diósd cuts 30–40 m deep. Shrubby steppe grassland covers most of it, with about 400 plant species, 45 of them protected.

Grazing kept the plateau's steppe grasses open for centuries until the forest was cleared. In the 20th century it served military purposes, then became an illegal dump; the XXII district section was cleaned and protected in 1999. A further 148 hectares in Törökbálint and Budapest XXII gained national protection in December 2011, bringing the total to nearly 300 hectares.

The plateau's name comes from Tétény, the historic district at its foot. Its dry grasslands were kept open by centuries of grazing, and since 2005 a study trail has led visitors through the protected steppe. Diósd's old underground limestone quarries left large cave-like chambers, including the Diósdi Római-barlang and the Kaptárkő caves.

The protected area lies in Budapest's XXII and XI districts and in Törökbálint, Diósd and Érd. A nature trail was laid out in 2005. The terrain is a limestone plateau at about 200 m, cut by 5–10 m steps every 600–800 m; the Anna-hegy in Törökbálint reaches 267 m.

Diósd, on the plateau, hides large cave-like chambers left by underground limestone quarrying, including the Diósdi Római-barlang and the Kaptárkő caves. The Érd–Sóskút edge drops in 70–80 m limestone walls at Madár-szirt and Nyakas-kő.
