Tourism has been one of the most important branches of the economy in the Republic of Croatia for many years. The enormous success in tourism development, with the exception of 2020, which was affected by the Covid-19 virus, is evolving every year. The Republic of Croatia is investing more and more in tourism, whether it is in terms of material or human resources, and thus stands alongside the most famous European tourist destinations. The increase in the number of arrivals and overnight stays of foreign and foreign tourists certainly affects the GDP, as well as other branches of the economy, since it has almost the largest share in the entire economy of the Republic of Croatia. By joining the European Union, Croatia became more accessible to other countries (abolition of borders, etc.), and this step in Croatian politics also influenced the development of this extremely important economic branch. Domestic and international investments in tourist infrastructure, such as hotels, resorts, and marinas, have increased significantly, which raises the quality of the offer and services. Finally, the promotion of Croatia's cultural, natural, and gastronomic attractions contributes to the attraction of different profiles of tourists, which further enriches the country's tourist offer.
