An easy walk/ mountain bike ride with not so many spectacular views, but a glimpse into an amazing underground world.
The access road (via 4x4 only) to the wind-turbine park connects several caves, pits, and chasms. Those include a cave that has the largest discovery of cave bear remnants, a graveyard of ancient elephants, archaeological spots, and the river Suica's spring and sinkholes. This tour can be called the Walk in The Lost World.
Great views over Lake Busko and Duvanjsko Field are also part of this connecting trail.
Biking this trail with a proper mountain bike will leave you with enough time to explore chasms and caves along the way.
