Tired of being at home? Already ridden all bike paths in the area? Are you looking for an adventure?


Koll’s Treasure Hunt  is an outdoor activity that combines elements of orienteering, art,and puzzle solving<.

The hidden jars contain a notebook, a rubber stamp and a code to unlock the next clue. Finders can make an imprint of the jars’ stamp in their personal notebook, and leave an impression of their personal signature stamp on the « visitors’ book »— as proof of having found the box and letting other players know who has visited.

Try to find the hidden Koll Jars and discover not only some awesome bike paths but you also get the chance to win a family package from our online store.

Why ?

It is not only funny way to discover Luxembourg’s nature an bike paths but you can also win some awesome stuff.

For each completed hunt you will win 1 family package from our online store.

If you manage to accomplish every hunt you will win something you cannot even think of.
