Mountain bikes are usually used for mountain biking. But here it's a little different: Here you're riding inside the mountain! The disused Mežica mine makes it possible. Where lead and zinc were once mined, there is now a unique mountain bike trail network. The most important tool: your bike lights, preferably a helmet lamp (which you can borrow here if you don't have your own).
The newest highlight is even more extreme: Spanning five mining levels with an elevation difference of around 150 meters, the new Black Hole Trail offers you a serious thrill even when you think you've already seen or ridden everything. To ensure everything runs safely, you'll be accompanied by a guide on all trails – safety first, especially underground.
Biking underground is, of course, a bit special. But it's certainly practical: It definitely won't rain here. The "weather" here is generally predictable, as the temperature on the mine trails is a constant ten degrees. Long pants and a warm jacket are definitely a good idea, but you can safely leave the rain jacket at home.
You must register your mountain tour. This can be done by email or phone. Prices vary depending on the group size: 2-3 people pay €30 each. Up to 7 people, the fun costs €25 per person. Up to 14 people, it costs €22 per person, and larger groups add €20 per person.
After the tour, a visit to the Mežica Mining Museum is worthwhile.
Finally, here's a video with English bike pro Olly Wilkins, who has also been here and apparently had a blast:
