Seongsan Ilchulbong Peak, which is 180m above sea level, erupted underwater in the ocean about 5,000 years ago. This makes it a very rare case among the many craters in Jeju Island. Though people used to farm in the crater, it is now a natural habitat for 200 types of vegetation such as silvergrass and giant angelica, among others, as well as a natural habitat for a variety of wild animals. Seongsan Ilchulbong has long been considered one of the top scenic destinations in Korea. It attracts millions of visitors a year, many of whom climb to the top for the breathtaking panoramic view of the ocean, Udo Island, Hallasan Mountain, and the volcanic landscape of the east. It was designated a Natural Monument on July 19, 2000 and subsequently recognized for its outstanding geological value by UNESCO on July 2, 2007, when it was added to the World Natural Heritage List. The peak was also named a Global Geopark Network site in October, 2010.

Jeju Stone Museum is a museum and ecological park which shows general and systemic stone culture of Jeju Island, the homeland of stones. The Jeju Stone Museum, Exhibition Hall for Jeju Stone Culture, and traditional thatched-roof house of Jeju Island took 7 years to complete. The park open on June 3, 2006. Construction at the park finished in February 2021, after 21 years. The Jeju Stone Museum is very big, since you will be able to see all the stone culture of Jejudo Island in one place, so it is good to have a relaxed schedule to enjoy it. There are 48 Dol Hareubang, a Stone Pagoda to repel evil forces and misfortunes, Jeongjuseok, which acted as the front door for Jeju houses since there were no thieves, and Dongjaseok, which was placed around the tomb to soothe the grief of the deceased, which shows the afterlife view of Jeju Island, are installed in the Outdoor Exhibition Space, and it is a natural and cultural rest area.

Seopjikoji, which is located on the east coast of Jeju Special Self-Governing Province, is a beautiful coastline filled with canola flowers during the spring, Seongsan Ilchulbong Peak rising up in the background, and the stunning Sinyang Beach nearby. Here you can see the traditional beauties of Jeju, such as a vast land filled with canola flowers growing on the hill, Jeju ponies grazing peacefully, beautiful rocky cliffs, and the legendary Seonbawi Rock standing in the middle of the ocean. What makes Seopjikoji different from other coasts in Jejudo Island is that it is made of red volcanic ash called “scoria”, and possesses strange rock formations that only show themselves when the tide is low are unique. It's the filming site for movies and TV dramas like "The Legend of Gingko," "The Uprising," "Cheonilya," and "All In."

Sangumburi Crater differs from the 360 or more parasitic cones of Jeju in that it was not formed when the materials ejected from the eruption stacked. Instead, it is a maar-type parasitic cone that was formed as a crater with a hole in it when many materials were ejected. The inner area is 300,000㎡, while the interior bottom circumference is 756m, and the exterior circumference is 2,070m. Nearly vertical, the crater is approximately 130m tall, making it slightly larger and deeper than Hallasan Mountain.

The first written record of Jeju's haenyeo diving women goes back to 1629 and is stated as a "潛女(Jamnyeo)" in the 『Description of Jeju’s Natural Features』 and 『Collected Works of Guchang』, by Lee Geon. Jeju Island's haenyeo diving women were the main breadwinners in the local economy through diving and farming. In doing so they contributed greatly to the development of Jeju Island. They are a symbol of industry and toughness, but it is also true that they have generally been undervalued in society. The Jeju Haenyeo Museum was built to help re-evaluate haenyeo culture in Jeju and record, preserve and provide education about their significant contributions, socially, economically and historically. On display are informative exhibits with information regarding the local environment, fishing villages, folk culture, and fisheries industry, with the unique haenyeo culture at the center of it all.
