It has been a centuries-old tradition in Mostar for young men to jump from the old bridge and plunge 24 meters into the Nerertva river. Considered an extreme sport because of the shallow and icy waters of the Neretva, it takes a trained driver approximately 3 seconds between diving from the bridge before hitting the water. This practice has been going on since the time the bridge was built with the first dive recorded in 1664. A diving competition is held every summer since 1968.
