Designated as a natural monument, Bijarim Forest is a group of about 2,800 nutmeg trees between 500 and 800 years old. They are 7-14m in height and 50-110cm in diameter. This is the largest nutmeg tree forest in the world. In the middle of the forest is an 800-year-old tree, called ‘Ancestor tree of the Bija trees.’ The tree is the oldest tree on Jeju-do with a height of 25 meters and girth of 6 meters.
The trees emit a lot of phytoncide, which is said to strengthen the immune system and natural healing ability of the human body. Nutmeg tree blossoms and the oil are said to have been used as insecticides in the past. There are also rare orchids and plants growing in the forest. A walkway through the forest has been installed for visitors to enjoy a stroll through the wonderful forest.
