만장굴( Manjanggul Lava Tube) Of all the oreum on Jeju, Geomunoreum is the only parasitic cone to be designated as a UNESCO World Natural Heritage site. The oreum holds over 20 caves within its body, although only Manjanggul Lava Tube is open to the public. With its profoundly mysterious and grand appearance, taking a step inside the cave is like stepping into Hades’ underworld. Follow the tunnel of articulate lava rock formations, and you will soon reach a giant rock pillar that indicates the end of the cave. The cave’s temperature fluctuates within 11-21℃ regardless of season, allowing visitors to enjoy the magnificent cave all year round If Manjanggul Cave is closed (on the first Wednesday of every month), Jeju Haenyeo Museum will be offered as an alternative tour

산굼부리(Sangumburi Crater) 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.In autumn, when the ridges of Sangumburi Crater are coloured gold by waves of silvergrass, the planted cedar becomes the dominate species that take up most of the eastern and western slopes, with Sawtooth oak in the surrounding area.Furthermore, Korean Fir has been planted to form a forest path. Excluding these lush forests, colonies of Eulalia grass cover large patches of the crater.

월정리 해변(Woljeong-ri Beach) Well known for its beautiful scenery, white sand and emerald water, Jeju Woljeong-ri Beach has a road filled with tea houses and coffee shops.  This is a great stopover during your trip to Jeju Island, and one of few places to enjoy an exotic view.

성읍민속마을 (Seongeup FILK Village) The entire village, which preserves the living site of the people of old Jeju, has been designated as an Important Folklore Cultural Heritage. Though it can be considered a folk village of sorts, it differs from regular folk villages in that people still live in it to this day. The village residents act as volunteer guides to offer visitors all sorts of information. The Saw-leaf Zelkova and Japanese hackberry in the centre of the village are worth taking time to see.

해녀박물관 Jeju haenyeo are the strong mothers of Jeju and the spiritual pillars of Jeju residents. Also, the life of the Jeju haenyeo community is a model that humanity should aim for. Jeju haenyeo formed a merit-based community and democratically decided through discussions. She not only cared for the elderly and infirm, such as Halmang Badang and Geseok, and raised funds with her material profits to contribute to society, such as villages and schools. She also came up with various contraptions to coexist with the sea, such as beach sweeping, gold snatching, and dialysis. Jeju haenyeo culture was recognised for its value and was registered as a UNESCO Intangible Cultural Heritage of Humanity on November 30, 2016 (local time). If Manjanggul Cave is closed (on the first Wednesday of every month), Jeju Haenyeo Museum will be offered as an alternative tour

It is Jeju's representative traditional market, located near Jeju Airport, and is popular with many people.

As a K-drama filming location, it is a beautiful place with a view of Seongsan Ilchulbong in Jeju. Couples or families can take a leisurely stroll

If you walk along Jeju Olle Course 19, you will come across Hamdeok Beach, which has an emerald jewel. Hamdeok Beach, located in Hamdeok-ri, Jocheon-eup, Jeju-si, is also called ‘Hamdeok Seoubong Beach’ because of Oreum (Seoubong Peak) standing right next to the beach. It is only 20km away from Jeju Airport, but the moment you arrive here, you feel like you are in another country. The tall palm trees that welcome you from the entrance, the emerald sea that contrasts with the white sand, the clear water and white waves that make even the sand and seaweed transparent are like that. Among the numerous beaches in Jeju Island, if you choose three places with the most beautiful sea colour, it is definitely Hyeopjae Beach, Gimnyeong Beach, and Hamdeok Beach. The water is clear and the water depth is shallow, so it is also a good summer resort for families. The west side of the beach is connected by an overpass, so you can experience walking on the sea.

A short drive from Seongsan Ilchulbong Peak will take you to Cape Seopjikoji. The name comes from the Jeju dialect for a “Cape of Small Land” due to its peculiar cliff formation that protrudes into the ocean. The picturesque harmony of the hill and ocean attract tourists all year round. You might even be able to sight Jeju ponies grazing on the field of grass.Walking northeast along the cliff, you will arrive at Bulgeunoreum Parasitic Cone, offering an exquisite view of a white lighthouse with the dark blue sea in the background. Additional noteworthy attractions of Cape Seopjikoji are the Glasshouse and Yumin Art Gallery, two masterpieces designed by world-renowned architect Ando Tadao. The two buildings blend in remarkably well with the surrounding nature.
