In the middle ages, water was scarce, and les bisses took a central role in developing agriculture and allowing the villages to prosper. Hence, les bisses are an important cultural symbol for Switzerland, proven with an honor nonetheless than having the Grand Bisse d´Ayent depicted on the 100 Swiss franc bill.
To experience a bisse firsthand, I took a trip to the Torrent Neuf in Savièse, a location old as dirt, first built in 1430 when knights in shining armor roamed the valley and princesses leaned from balconies in the Sion castle. Beautiful terraced vineyards and apricot farms still lie below, just like they would have been 700 years ago.
For this tour I am accompanied by a true local expert, the Valaisanne mountaineer and certified mountain leader, Noemie Evequoz. She will guide me through the walk, and as a biologist, she will elaborate on the rich flora and fauna along the path.
