There are numerous rural settlements in the Kupa valley that are mostly abandoned or are used solely on the weekends. The most important among them is Razloge, which is one of the most active villages in the Park, and both the Park and the people living there have development plans.
The dominant construction style in settlements within the Park is characterized by so-called montane (“goranske“) houses, mostly built of stone and wood, the two materials locally available. Houses are roofed and partially paneled with wooden shingles or planks. One of the most valuable houses of this type is situated on the Leska Learning Trail.
