This 1.2 km trail starts near the Prienai polyclinic bus stop and leads through forest to the Velniabliūdis raised bog, described as the only raised bog in the Prienai bend of the Nemunas. A wooden boardwalk crosses the peat past sphagnum moss, sundews, cranberries, and cottongrass, and the bog hosts smooth snakes, grass snakes, and birds such as the yellow wagtail; peat dug here historically supplied the mud-bath treatments at nearby Birštonas resort.
