Nautical tourism in Croatia is a very important part of the tourism offer, crucial for the economic development of the country. The Croatian Adriatic coast, with over 1.200 islands, islets and reefs, provides ideal conditions for the growth of nautical tourism, while its clear waters and favorable climate make it one of the most attractive destinations in the Mediterranean. Croatia has a well-developed infrastructure for nautical tourism, with numerous marinas, ports, and harbors, many of which hold the Blue Flag, signifying a high level of environmental protection. The most popular nautical destinations in Croatia are Dubrovnik, Split, Zadar, and Šibenik, as well as the islands of Hvar, Korčula, Brač, and the Kornati. Nautical tourism has a significant impact on the country's economy, bringing in substantial revenue not only through boat rentals but also through tourists' stays, restaurants, and other local services. This type of tourism attracts visitors with higher spending power, which positively affects local communities. Challenges such as overcrowding in certain locations during the summer season, marine pollution, and irresponsible behavior by boaters require careful management to ensure sustainable development. The introduction of ecological standards and regulations, as well as the promotion of responsible tourism, are essential for preserving natural resources and further developing nautical tourism in Croatia.
