Not all of Switzerland is equally mountainous, but fortunately, the area around Basel offers some beautiful hikes.
One of them is the hike from Langenbruck (meaning long bridge) to the Belchenflueh summit. You easily get there by car or by bus (Postauto).
It’s a 4.5 km hike covering 400 m of elevation leading along yellow speckled meadows and through old mixed forests.
