The tertiary sector of the economy is dominated by tourism, as the branch of the economy with the largest potential, whose development helps to develop other industries in the service sector such as catering and trade.
Unfortunately, tourism in Herzegovina is a real example of underutilized potential of natural resources. Incredible natural beauty, good climate, favorable terrain, geographical position, a turbulent past, crossroads of various civilizations, cultures and religions, are just some of the trademarks of this region that tourists can enjoy, but aren't presented in an appropriate manner, which reduces the revenue brought in by tourism significantly compared to its potential.
The Old Bridge in Mostar, over the river Neretva, which at the time of its construction was the largest single-arched construction in the world, is today element on the UNESCO World Heritage List, as well as the authentic parts of the old city of Mostar, which date back to the Ottoman rule of this land. They can be considered the biggest jewels of tourism in Herzegovina - bringing in many tourists every year. However, capacities for religious and cultural tourism in Herzegovina are much larger than that.
Alongside Međugorje - which is already a globally known pilgrimage site,
there are numerous other religious and cultural monuments which deserve greater attention, such as Karađoz-bey's and Roznamedži's mosques in Mostar, the tekke in Blagaj, an Orthodox church carved into the rock which is also ranked 4th in the world for the value of its frescs, the Franciscan monastery in Šćit, the monastey on Humac, the monastery in Trebinje, the tower in Počitelj, ancient Ilyrian cities and Roman roads in Livno.
Due to its geographic position, climate and the amount of sunny days summer tourism certainly represents a significant share of tourism in Herzegovina. In order to better use it, it is necessary to offer visitors adequate tourist programs which would keep them in Herzegovina for a longer period, which is certainly possible with its natural reseources. Rafting on the river Neretva, canoe-safari and waterfall Kravice on the river Trežiat, Boračko lake, the swamps in Hutovo blato, hiking, climbing, sports-tourism and eco-tourism, as well as visiting historical and cultural monuments in Mostar, Blagaj, Čapljina, Trebinje, Široki Brijeg are just some of the possibilities which, with planned development and investment, could improve the economic development of the region. Diverse plants and wildlife, and ski resorts in Kupres and Blidinje provide potential for even greater development of winter, mountain and recreational tourism, as well as rural and eco-tourism.
