Trebinje has a potential for urban and rural tourism development, same as for cross-border tourism as it is placed on less than 35 km from Dubrovnik (Croatia) and 80 km from Kotor (Montenegro), both UNESCO sites. It is one of only few cities in Bosnia and Herzegovina with well-preserved urban ensembles originating from different historical and cultural periods. In the inner part of Trebinje are also registered monuments originated from ancient periods that are still undiscovered, but that easily can be integrated into the tourist offer. All these layers of urban life together with the prominent natural framework of the river, the mountains and the flatlands, have created authentic and attractive places to visit. Rural areas of Trebinje are favorable for hiking and rural tourism. On the mountains around the city there are more than 10 fortresses originating from the XIX century and various sites of gromule (early-medieval Slavic graveyards).
The villages around Trebinje still have traditional houses in stone and small-agricultural activities are preserved. In one of the villages the most important orthodox saint in the region was born, which recently gave rise to religious tourism. Nearby Trebinje there is also a medieval monastery famous for its wine production. Besides wine, Trebinje is famous for its cheese and honey. It is also recognised as cultural centre with art colonies, theatre, music and folklore festivals that take place thoughout the year.
