This region characterizes the diversity of its above-ground and underground waters. The source of the Buna is one of the largest and most beautiful in Europe. It is the finest example of an underground karst river. It flows out of a 200m cliff wall and single-handedly creates the Buna River. Unsurprisingly, the Ottoman sultan was impressed, and ordered a tekija to be built right next to it. This 16th century house/monastery was built for the Dervish cults and is still one of the most mystical places in all of Bosnia and Herzegovina. It is open to visitors all year round and serves cold drinks, tea and Turkish coffee in a beautiful garden overlooking the source of the River.

This unique settlement, listed as a UNESCO heritage site and recent reconstruction has returned the town to its original form. It was first mentioned in 1444 but some documents show that it was built in the late 14th century upon the order of the Bosnian King Tvrtko. Besides its stunning oriental architecture and Ottoman feel, Pocitelj hosts the longest operating art colony in southeast Europe.

Međugorje, or Medjugorje, is a town located in the Herzegovina region of Bosnia and Herzegovina, around 25 km (16 mi) southwest of Mostar and close to the border of Croatia. The town is part of the municipality of Čitluk. Since 1981, it has become a popular site of Catholic pilgrimage due to Our Lady of Međugorje, an alleged series of apparitions of the Virgin Mary to six local children; church authorities, however, have not approved the apparitions for public veneration

The gem of this region is the crystal-clear water of the Trebizat River. Southeast of Ljubuski are the Kravica Waterfalls. Stretching over 120m across and tumbling down 25m, Kravica is one of the largest waterfalls in Herzegovina and certainly the most impressive one. The waterfalls have a natural pool dug out at the base of the falls by the constant rush of water. It is a favorite local swimming hole with picnic area, café and even a place to pitch a tent if you like. The best time of year for visiting is springtime when the waterfall is at its fullest and the arid landscape turns a bright green.
