Tourism is a set of relationships and phenomena that arise from the movement of tourists outside their domicile for more than 24 hours, provided that they do not make money from this movement. Tourism and sports have not only become two very popular, global, social activities that have evolved markedly from the twentieth century to the present day, but both activities have become part of our global culture. Tourism and sports are interrelated socio-economic phenomena. A selective form of sports tourism includes for the motive of travel sports. Sports activity is an increasingly common reason for rest, but also for the lifestyle of today's man. Sports tourism therefore encompasses user roles from top athletes, recreational athletes to passive spectators. Recreation and leisure activities have become the main motives of tourist trips leading to the conclusion that vacation travel has become a part of every individual’s lifestyle. The offer of sports and recreational facilities in the most economically developed region of Croatia, Istria, is focused on several different tourist destinations, of which the most prominent are the cities of Pula, Poreč, Rovinj and Umag. The facilities offered to visitors are mostly related to summer activities that take place at sea, and include diving, fishing, sailing and beach volleyball. Tennis, as a sports and recreational activity, is extremely represented, which coincides with the coexistence of numerous tennis courts, but also the popularity of the tennis tournament in Umag, which traditionally takes place every year, bringing the world's best tennis players, and thus a large audience. Given the comparative advantages we have, sports and recreation should actually be promoted as one of the key products given that it can be developed just as successfully in the mountains, spas, but also at sea.
