Hin Sam Wan, also known as Three Whale Rock, is an intriguing and unique rock formation in Bueng Kan Province, Thailand. It is 75-million years old and gets its name from the resemblance of two rocks to a family of three whales - mother, father, and baby. The whale shapes are only visible from certain angles and while visitors can access the mother and father whale rocks by foot, the baby whale can’t be reached. Hin Sam Wan is a must-see for adventurers, nature lovers, and those seeking to escape the hustle and bustle of city life.
