The field is surrounded by limestone hills and dotted with small villages, old stone houses, and fertile farmland. The Trebišnjica River flows through the field, influencing both its landscape and hydrology.

            A historic narrow-gauge railroad once crossed the valley of Popovo Karst Field. Built in the early 1900s by the Austro-Hungarian Monarchy, this railway, served by the steam train popularly known as "Ćiro", connected Mostar and Dubrovnik. It was built primarily as a strategic military facility, linking the southern Adriatic ports with the hinterland and Central Europe. For the people of Popovo Karst Field, this was a "railway of salvation," as it brought economic opportunity and overall progress.

            When the railway was closed in 1976, the entire region lost much of its vitality. Most villages in Popovo Karst Field are now abandoned, and the remaining population consists mainly of older residents engaged in cattle breeding and agriculture.

            At the edge of Popovo Karst Field, near the karst sinkholes known as ponors, a series of traditional water mills once harnessed the power of disappearing rivers. These ponor mills were ingeniously built to operate with the fluctuating water levels typical of the karst landscape. Using simple but effective wooden mechanisms, local people ground grain and produced flour for surrounding villages. The mills were an essential part of daily life and symbolized the community’s adaptation to the valley’s unique hydrology. Most of them ceased operation in the mid-20th century, and today only the partially preserved stone remains testify to this once vital aspect of local life and industry.
