Lavreotiki Geopark covers the whole municipality around the port town of Lavrio, about 60 km from Athens, where the ancient Athenians mined silver. The area holds around 1,000 old mining galleries and as many shafts, and seven geo-paths lead walkers past rock formations and former mine sites.
The district has more different minerals than any other place on Earth, so it suits kids who collect rocks.
