Jeju's most eccentric and internationally infamous attraction and almost a reason in itself to visit Jeju, this bizarre sculpture park was created by graduates of Seoul's Hongik University. Few of the more than 140 exhibits are generally shocking, and it makes for some interesting holiday snaps that you won't want to show your parents. Although you will likely see some Korean families in the park, this is one where you should definitely leave the children at home or in the attached playground. It has a sex shop attached, naturally. Elsewhere on Jeju you will find phallic representations are an ancient symbol of the island. Amusingly, the Chinese government prevented the opening of an imitation loveland in Chongqing.
Jeju Loveland is an outdoor sculpture park which opened in 2004 in Jeju Province, South Korea. The park is themed around sex. It plays sex education films and has 140 sculptures of humans in various sex positions. It also has other elements such as large phallus statues, stone labia, and hands-on exhibits such as a "masturbation-cycle". The park's website describes the location as "a place where love oriented art and eroticism meet".

신비의 도로
Called the Mysterious Road or the Goblin Road, this is a strange place where if you park your car on a downhill road, the car that has to go down does not go down, but rather steps back toward the uphill. In fact, the side where the uphill road is visible is a downhill road with a slope of about 3 degrees, so it seems to be going up by a simple optical illusion. Due to this phenomenon, Dokkaebi Road has become a tourist attraction due to word of mouth, and various safety facilities are being added (as of Oct 2022) to prevent accidents caused by it, and a tourist park is expected to be created soon.
한라수목원
Home to nearly 1,100 species of plants, including native Jeju flora and exotic subtropical species.
넥슨 컴퓨터 박물관
Apparently Korea's first dedicated computer museum, housing over 4,000 working examples of antique computers and video games.
이호테우 해변
It is close to Jeju Airport, and it is enough distance to ride a bicycle. There are white and red pony lighthouses, the slope of the beach is gentle, and there is a pine forest nearby, so it is a good place to enjoy the scenery and take a walk.
제주민속자연사박물관
The museum is divided into four exhibition halls: natural history, folklore, special resources, and an audio-visual room. It contains natural history of the island as well as relics, animals and plants that are found around the island. The stuffed animals are popular among children.
용두암
A large piece of volcanic rock said to be the solidified remains of Yimugi, a water dragon. Whilst the legends behind just how he got himself turned to stone in that position vary, it hasn't diminshed his influence, as the surrounding suburb is called Yongdam by extension: literally "Dragon's Head Rock". Just about 100 m to the east you can find the lesser known, but probably prettier Yongyeon Pond, a picturesque canyon straddling a pleasantly turquoise pond with a pavilion perched overhead. Again, a dragon features heavily in the legendary history of this site, but simply that it visited. A festival is held here in May. If all this talk of dragons is making you want to sit on a horse for some reason, then there is an old guy out the front who aggressively and inexplicably offers this service for a fee. Both sites are lit up spectacularly at night.
