The whole family can go on a treasure hunt in Aeschi bei Spiez. Various questions are hidden on the treasure-hunt trail that the family can find and answer together. Once the treasure hunters have answered all the questions correctly, they can pick up a reward at the tourist office.

The treasure hunters collect their treasure map at the tourist office and then head off on the three-hour trail. The simple route takes them over meadows of flowers and along the edges of forests. A number of stop-off points with questions are hidden along the way. The questions are designed for children from the age of around six. While little ones are busy answering the questions, parents can enjoy the glorious views of the Niesen and Lake Thun. As soon as they have found all the answers, the family heads back to the tourist office, where each treasure hunter can choose a reward from the treasure chest.
