For visitors, probably the most popular aspect of the 'pyramid' archaeological zone is the Ravne labyrinth. A dozen or more kilometres of tunnels supposedly date back many millenia. Though later filled up and only re-excavated over the past decade, guides suggested that they were originally excavated by the same super-culture that built the 'Pyramid of the Sun'.
Believers assert that monoliths found here give healthy vibrations, that water inside is unusually pure and that 'negative radiation' probably made the site a place of healing. A half-hour hard-hat tour through the ever-growing network of accessible tunnels is undoubtedly a fascinating experience. You'll get over 200m into the mountain and see large smooth stones inscribed both with runes and with what just might be an ancient map of the labyrinth.
From the bus station cross the bridge, pass the Hotel Piramida Sunce and continue 2km towards Kakanj (road initially called Branilaca) then turn left after the Bingo Hypermarket and climb 500m up a tiny asphalt lane.
