Mase is located above the Borgne River in the Val d'Hérens, at 1345m. Its well-maintained historic farmhouses lend authenticity to the village. The deserted villages of Sevanne and Marguerona are extremely interesting.
Traditions are honoured in Mase, for example the “Night of Fairy Tales” in mid July. Storytellers can be heard throughout the town, followed by a glass of wine, some soup or a piece of dessert. Vacation in Mase is a memorable experience.
