The castle is constructed from hexagonal basalt columns, which were once considered a geological curiosity in Europe.
The site features a Stone Waterfall (Kamenný vodopád) consisting of cooling lava columns up to 4 meters long.
Construction began in the 13th century using basalt blocks quarried directly from the hill it sits upon.
The state border between Slovakia and Hungary runs through the castle courtyard.
The basalt columns were formed approximately 4 million years ago during volcanic activity in the region.
The castle was occupied by Turkish forces during the 16th and 17th centuries before being liberated in 1593.
The pentagonal castle tower was designed to deflect cannon fire by minimizing flat surface angles.
The access path is part of a pedagogical nature trail detailing the geological history of the Novohrad-Nógrád UNESCO Global Geopark.
Šomoška Castle is a 13th-century border fortress situated directly on the border between Slovakia and Hungary, constructed primarily from volcanic basalt. The site is most famous for its 'Stone Waterfall,' a rare geological formation consisting of vertical basalt columns created by cooling volcanic lava. The castle was built following the Mongol invasion and was strategically positioned to protect the route to Central Slovak mining towns. It features a unique pentagonal tower and a well-preserved renaissance-style gatehouse. The ruins overlook the Cerová vrchovina Protected Landscape Area. Visitors reach the castle via a nature trail that passes through the surrounding forest and the basalt quarry. It was significantly restored in the 1970s and 2000s to stabilize the structure. The border runs through the castle area, allowing visitors to walk between the two countries within the complex.
The base of the Stone Waterfall formation, which provides a clear perspective of the basalt columns.
Wear sturdy, closed-toe hiking footwear, as the path is steep and the basalt terrain is uneven.
Bring a camera with wide-angle capability to capture the vertical basalt columns of the Stone Waterfall.
Check the weather forecast, as the forest trail can become muddy and slippery after rain.
Do not attempt to climb or dislodge any basalt rock formations, as this is illegal and dangerous.
Open daily during the main tourist season from spring to autumn; restricted access or closures may occur in winter due to ice or snow.
Respect the cross-border nature of the site and adhere to the marked trail boundaries to protect the geological formations.
