Prerast Samar, natural bridge in Serbia
Prerast Samar is a natural stone arch formed from limestone in the Kučajske planine mountains of northeastern Serbia. The curved opening spans a narrow valley and represents what remains after cave roofs collapsed over thousands of years, with nearby caves ranging from 68 to 215 meters long and adding to the geological complexity of the site.
The arch formed over thousands of years through water and chemical erosion of limestone rock. What is visible today as an arch was originally part of an underground cave system whose roof collapsed, leaving behind the curved stone bridge structure that stands now.
The site is accessible by car or bike via rural roads and trails, making it suitable for a day trip from nearby towns. Visitors should come prepared for a short walk, bring water and a camera, and respect the natural environment.
Multiple underground caves exist at this site, including one roughly 68 meters long and another reaching 215 meters, revealing hidden complexity beneath the surface. These underground channels and voids show different stages of natural erosion, with some containing perennial underground rivers that flow year-round.
