On the bank of the river Linkava in the Linkiava hydrographic reserve peacefully lies a huge boulder with a spectacular name Rapolas. Due to its spectacular size: 14.54 m max horizontal volume, 2.55 in height, 5.14 m in length and 4.18 m in width, in 1964 it has been announced as a natural monument. It is believed that the unusual name was given to the stone according to the name of the local farmer who lived nearby. People of Krekenava also call the stone the brother of Puntukas because of its impressive size.
