Winter swimmers from the Czech Winter Swimming Union will dive into the Vltava River on Three Kings Day. This takes place every year on January 6, at noon, under Charles Bridge, at the spot where St. John of Nepomuk was thrown into the water. The winter swimmers will dive into the Vltava from the deck of the Vodouch boat at the fifth bridge pier of Charles Bridge (counting from the Old Town side). They will swim about two hundred meters towards the Charles Bridge Museum to the landing stage under the last preserved arch of Judith Bridge. More than forty athletes (some from abroad) will swim for the ferryman's punch at noon. Not only winter swimming enthusiasts are invited, but also anyone who wants to support the winter swimmers. You can watch the entire event from Charles Bridge and Křižovnické Square. Schedule 11:45 Departure of winter swimmers for a photo shoot in front of the Charles Bridge Museum 11:55 Boarding of Vodouch boats at the Judita pier and departure on the Vltava River 12:00 Winter swimmers enter the water and swim back to the pier under the last preserved arch of the Judita Bridge The tradition of this event began in 2010, when it was first organized by the Czech Winter Swimming Union and the Charles Bridge Museum. From the very first year, it has not been a competition, but a gathering of winter swimmers and a commemoration of historical events and places associated with the Vltava River. St. John of Nepomuk is the patron saint of bridges, fishermen, millers, swimmers, and all crafts related to water. Judith Bridge was the first stone bridge in the Kingdom of Bohemia, with 20 arches and a length of approximately 500 meters, but in 1342 it was swept away by a great flood and replaced by a new stone bridge — later known as Charles Bridge.
