The danger of mass tourism and its seasonality and all the consequences that such a form of tourism brings with it is especially emphasized. Some places on the Adriatic in the summer months become unbearable for tourists who come on vacation as well as for the domicile population. The danger of spatial devastation was also pointed out.Sustainable tourism development rests on three pillars: economic sustainability, social responsibility and environmental protection.Successful implementation requires the cooperation of seemingly opposing sectors, such as tourism construction and space protection. There are many bad examples of non-cooperation of the mentioned sectors in Croatia and that is why we must approach further development carefully and professionally so that further spatial “pollution” does not occur. If we look through the history of the construction of cities and settlements, we will see that in the past much more attention was paid to the culture of construction and materials that were appropriate to the climate.Sustainable tourism means involving the population and coexisting with tourists because they are just coming to experience, feel and taste what they do not have in their area. Cooperation between service providers and local producers is highly valued and sought after today. Rural households that, in addition to agricultural activities, also offer the service of accommodation and food, must get their place in the tourist offer. It is not uncommon for a fast food product to be more expensive than a domestic and healthy product of an agricultural household that has only produced that food. In the context of the development of continental tourism, education is needed as well as strategic assistance in sustainable development.Based on the lectures and interactive panel discussion, conclusions were reached according to which the philosophy of sustainable tourism should be promoted at all levels of society, integrate tourism development stakeholders to adopt specific sustainability projects (TZ, JLS, LAG, associations…), create, promote and implement small projects “Sustainable tourism in practice ”and certainly legally regulate and improve mountain tourism as well as other selective forms of tourism in Croatia, following the example of good examples of developed countries.
