The Black Hole Bike Festival is a multi-day mass recreational/competitive event, the likes of which Slovenia has never seen before. In it we managed to bring together the best that Koroška region has to offer in mountain biking. Having become one of the favorite tourist mountain biking destinations for bikers from all over the world in recent years, it certainly has a lot to boast.
