"The planet route is an experience for the entire family. Each kilometre of the hike corresponds to one billion kilometres in the solar system, providing a glimpse of the infinitely vast cosmic dimensions. Information sign posts convey the most important characteristics for the adults. Thanks to the many fireplaces, children don't miss out either. The view of the Aare river and the crown of the Alps is a highlight for one and all."
