BHAK, Tuesday April 29th
On Tuesday morning, we visited the Hartberg ecological park situated at about one hour-drive from Graz. This scientific park has many ludic workshops dedicated to the Energy's environmental issues, to the global warming and to the rising water levels.

In the afternoon, we visited the Zotter chocolatery which is engaged in an eco-friendly policy and a fair trade with cocoa producers everywhere in the world. More than a hundred different chocolate flavors could be tested to delight the taste buds of the finest gourmets... and to torment the stomachs of the geediest.
