Geoparkos túra a Föld napján.
The impressive castle hill overlooks the surroundings by roughly 130 m.
It represents an exposed diatreme (feeding channel to the surface maar which hasn’t been preserved). The diatreme hill is formed by basaltic tuffs and breccias pierced by younger basaltic dikes. The radiometric age of the basaltic dike is 2,75 } 0,44 Ma. (Late Pliocene). The locality is valuable for its scientific and landscape studies. The first historic document, mentioning the castle, dates back to 1245. It was a royal castle and seat of an estate. Twice captured by Turks, it was reconstructed in the 17th century and devastated since 18th century.
Az erről szóló megállapodást a Cseres-hegység Tájvédelmi Körzet alapításának 30. évfordulóján írták alá.

A geoparki helyszíneket járták be a túrázók
From the starting information board located in the centre of the village of Szarvaskő, the northern wing of the nature trail leads to the Vár Crag and subsequently to a pike of the Tardos Crag called Akasztó (back and forth: 2.4 km). Stations No. 6, 7, 8 and 9 give an introduction to the typical rock exposures of the gorge valley of the Eger Stream (schist, diabase, deep-sea pillow lava) whereas station No. 10 draws attention to the panorama seen from the Castle of Szarvaskő built in the 13th century. The information board of station No. 11 demonstrates the living world of the siliceous grasslands of the Akasztó Hill. The ring-road designated to the south of the village (6.4 km) goes through the Mocene crag outcrop of the Hegyes-kő lane, the Denevér Adit (wehrlite body) and the Quarry of Tó-bérc. The information board of this latter geological exhibition site presents the diallage rock intrusion intruded into the deep-sea sedimentary complex formed during the Mid-Jurassic about 166 million years ago.
The Petőfi Walkway
The several decade-long relationship between humankind and landscape can be traced in the walkway linking the castles of Somoskő and Salgó. In addition to introducing the relation of illustrious ancestors, one can get in touch during this walk with one of the basic field of nature conservation, i.e. bird protection as well as coal mining playing a decisive role on the foundation of the town. In the Birds’ Park of Eresztvény, a series of boards entitled as ‘Bird-friendly garden’ by the MME BirdLife Hungary can also be seen.
