In the end, It will be made a retrospective of the whole story. Barcelona is a Mediterranean city located in the northeast of Spain with a rich past. It had super preconditions for multi-level development. First of all, there is the economy which is one of the most influential in the country, then the urbanism of the city which has gradually developed over the past and the favorable climate that has conditioned the development of tourism. The pleasant climate, many hours of sunshine, kilometers of sandy beaches and many historical sites are attractive and attract more and more tourists from year to year. In the beginning of the development of tourism in Barcelona, the city gradually built and adjusted to trends until it grew into a European metropolis. The city has a lot to offer. Starting with hospitality industry or entertainment. It is affordable for people of varying levels of income. However, the sudden transformation of tourism into a mass phenomenon has shown an impact on economic, cultural and environmental factors. Of course, the positive factors are clear and visible, but the problem is the negative factors that tourism carries with it. High revenues, local involvement and good infrastructure are not enough to cope with tourism as a mass phenomenon. An underdeveloped destination management plan and strategy has led to the problems Barcelona faces today. Too much tourism is gradually destroying the integrity and appearance of the city itself. The problem is the overcrowding of urban facilities, construction of hotels and similar structures by the sea. Air and water pollution and noise are also a problem. The locals are forced to take radical measures, first and foremost, for their own livelihood, which leads to misbehavior and sends a bad image of Barcelona as a destination. Despite the increase in service prices and the radical behavior of the locals, the number of tourists is not decreasing. However, for now, this way of managing a destination works, but the question is whether it will be maintained in the long run.
