The aim of the paper is to explain theoretically and show on a practical example the possibility of including diving tourism products in the offer of travel agencies. Diving tourism is a type of selective form of tourism that is classified as adventure tourism. Diving tourism has seen significant growth in recent years, both at the world level and in the Republic of Croatia. The Republic of Croatia, and especially the Split-Dalmatia County, have great potential for the development of diving tourism, since they are abundant with very attractive natural locations for diving, and extremely attractive diving sites refer to underwater heritage. Tourist diving services are provided by diving centers. There are a number of diving centers operating in Split -Dalmatia County that provide tourist diving services (equipment rental, organization of dives and diving courses) according to the highest world safety standards. On the other hand, travel agencies, as travel organizers, create their own products, travel arrangements as a combination of several individual travel services and products. Connecting d iving centers with travel agencies enables the professionalization of diving tourism products and opens up the possibility of creating products with more added value that significantly enriches the offer of a tourist destination and positively contributes to the overall development of tourism. Although the Republic of Croatia meets both the natural and infrastructural preconditions for the development of diving tourism, its full potential has not been fully utilized. Targeted marketing strategies with specific promotional activities can contribute to the further development of diving tourism in the Republic of Croatia.
