An adrenaline ride with headlamps through the underground tunnels of Peca.

Black Hole Trail

The Black Hole Trail is a unique, technically demanding adrenaline mountain biking adventure through the abandoned tunnels of the Mežica mine, designed for experienced cyclists and a recipient of the Slovenia Unique Experiences label.

A unique underground adventure for experienced mountain bikers.

The Black Hole Trail is a special challenge even for the most experienced mountain bikers. The trail runs through the abandoned tunnels of the Mežica mine. From the time the mine closed until the day the trail began to take shape, no human foot had stepped inside. The enormous halls were once filled with tons and tons of lead ore. This extreme adrenaline mountain biking trail represents an unforgettable adventure even for the most skilled and experienced mountain bikers. The trail is full of challenges and technically demanding sections. The path descends across five horizons and drops by approximately 150 meters in elevation. Along the way, you will also encounter very interesting flowy sections where you can relax a little and enjoy the views into the infinite blackness of the large halls. Naturally, any section that proves too demanding can be covered on foot.

Since 2023, the Black Hole Trail has been a recipient of the Slovenia Unique Experiences – Recommended by Slovenian Tourist Board label. It is a unique experience included in a carefully selected collection of experiences marketed under the Slovenia Unique Experiences quality brand, supporting the story of green boutique Slovenia and the I feel Slovenia brand.
