Puntukas is the second-largest boulder in Lithuania, a natural monument of the state. It is situated some 5 kilometres (3.1 mi) south of Anykščiai on the left bank of the Šventoji River. Next to Puntukas, the treetop trail of Anykščiai Pine Forest is arranged. It was believed to be the largest stone in Lithuania until the discovery of Barstyčiai stone in the Skuodas district in 1957.
