Orientation
In this activity teams made of mixed people from different countries had to find six letters that compose a secret word that the participants did not know. The super-secret word was Europe. Those letters where written on a piece of paper attached to a tree, there were also fluorescent vests to make the location of the letters more seeable.
Each team had only one map with the location of the letters, but nevertheless, it wasn't easy as the forest is very large.
