When one pictures visiting South Korea, one typically thinks of Changdeokgung Palace, the Seoul Tower, Gyeongbokgung Palace, and the Jagalchi Market– where travelers can indulge in the country’s largest collection of commercial seafood. What one doesn’t initially think of is a small island that is being recognized as one of the natural wonders of the world. But maybe you should.

Roughly 282 miles from South Korea’s capital city, Seoul, is Jeju Island (or Cheju-do, as the locals call it). Although the island is jam-packed with museums and cafes, it is also filled with beautiful wonders of nature. The island was created entirely through volcanic eruptions roughly 2 million years ago and consists mainly of basalt and lava.

One of their main attractions is Mount Hallasan which is the highest mountain in all of South Korea rising 6,400 feet above sea level. When hiked, this mountain–once an active volcano–contains gorgeous views of the freshwater lake formed in the crater of the volcano.

Another major attraction on the island is the many waterfalls, including the Jeongbang Waterfall, which is the only waterfall in Asia that plunges directly into the ocean. It is roughly 75 feet high and can stretch to 26 feet wide depending on the rainfall. There’s also the Cheonjiyeon Waterfall, which is especially popular for tourists in the evenings.

The Seongsan Ilchulbong, another natural wonder on the island, was created through hydrovolcanic eruptions in shallow waters, which created a bowl-shaped large crater. In the springtime, the fields surrounding the crater are filled with yellow canola flowers which, when viewed from the peak, are a truly spectacular sight to behold.
