The "Midsummer Festival of Saint-Cergue" celebrates the traditions of midsummer. This festival is an opportunity for the herdsmen to return to the mountains and share a convivial moment with their friends and the public. The event traditionally features a cow competition in the morning. The afternoon attracts visitors with local produce and cow fights. The day concludes with a supper and a country dance. This festival is open to all who wish to share in this traditional moment.
