This weekend marks the Frauenfeld Schwingfest. The event takes place every three years with the intent to crown the National Schwingen king. I heard that this year the Swiss Army has erected temporary seating for 60,000 spectators. The popularity of the event means that tickets are already sold out.
Surrounding the Schwigen grounds a Alperfest will be held. So even if you can’t get a ticket on eBay or Ricardo it still might be worth a weekend visit for some wurst and yodeling.
