Diviačia priepasť — locally known as 'Žomboja' — is one of the deepest and most spectacular karst caves in the Slovak-Hungarian Karst region, plunging 123.5 metres into the earth and hiding eleven magnificent chambers adorned with rich cave formations. It is the deepest cave on the entire Plešivská planina plateau, and a site of extraordinary scientific and natural value.

The cave sits in the south-eastern part of the Plešivská planina plateau, embedded in a classic Slovak karst landscape of open grasslands dotted with sinkholes and limestone fissures. Above ground, there is little hint of the dramatic underworld beneath your feet. The plateau has a quiet, almost timeless quality — golden in autumn, snow-dusted in winter, and alive with birdsong in spring and summer. The entrance to the abyss has been known to locals for centuries, lending the place an air of quiet mystery.

• Vidová village (starting point) — shortest approach, approximately 2 km to the cave entrance. Note: the cave itself lies within the cadastral area of Plešivec. Difficulty: moderate.

• The cave is closed to the general public — access is permitted only for researchers and cavers with official authorisation.
• Protected since 1986 as a National Nature Monument (Národná prírodná pamiatka).
• Located within Slovak Karst National Park and inscribed on the UNESCO World Heritage List.
• The cave is an important winter roost for lesser horseshoe bats and greater mouse-eared bats.

When Czech speleologists first explored the cave in 1964, they discovered a 3,000-year-old wild boar skeleton at the bottom of one chamber, covered in cave formations — and that remarkable find gave the cave its name: 'Wild Boar Abyss'.
