Venice will introduce a five-euro fee for day visitors to its historic center on 29 peak days, aiming to address overtourism. The initiative exempts overnight guests and certain other visitors. The system requires registration and a QR code, and aims to encourage tourists to visit on less busy days. The city also monitors visitor flow and has faced scrutiny from UNESCO over its efforts to protect the city. Critics argue that the fee is insufficient to deter visitors, and Venice has also implemented other measures to curb overtourism, such as banning cruise ships from inner canals and imposing limits on tour groups.
