This is the third cache in my challenge to other geocachers in the Geocaching Green Map project. You can read about it here. If you don't want to engage yourself in the project, just treat this as a normal cache :)
Ekocentrum is somewhat of a center in this cache idea. It is a quite busy area so you have to be careful!
The cache is a small black steel canister. PLEASE BRING YOUR OWN PENCIL
