Justistal
A closed valley above Lake Thun where the summer's cheese is divided among the farmers on one September day.
Updated 12 October 2026
The Justistal is a hanging valley above the northern shore of Lake Thun, closed at both ends and grazed each summer by cattle from the farms below. Its custom is the Chasteilet, held on a fixed day in late September: the cheese made on the alp through the season is brought out, stacked in the open, and divided among the farmers in proportion to the milk their animals gave, a share-out that has been run this way for centuries and is settled publicly in front of everyone. It is a working division of assets that has become an event, with food stalls and several thousand spectators, but the substance is unchanged. Outside that day the valley is quiet pasture with walking routes over to the Sigriswil ridge.
