Approximately 72% of the Earth is covered by the ocean, while land accounts for less than 30% of the planet we live on. Since most of the Earth consists of oceans, it is time to explore the remaining 72%. What kind of excitement awaits in the ocean, often called the garden of the gods?
There are countless seas around the world, along with many beautiful and famous diving points. South Korea is a peninsula surrounded by the sea on three sides. Naturally, the East Sea is considered the representative sea of Korea. Among its many locations, the sea of Gangneung stands out as a prime destination.
The waters of Gangneung feature a beautiful underwater environment and the largest number of shipwrecks in the country. Now, let’s set off for the ocean!

The sea of Gangneung has the largest number of shipwrecks in Korea. Gangneung City was the first in the country to initiate an underwater park project, and today several shipwrecks have been established as diving points within the Gangneung Underwater Park.
In fact, the shipwrecks in Gangneung are artificial wrecks, intentionally submerged vessels known as “wreck reefs.” Their primary purpose is to provide habitats for fish and marine flora and fauna. As a result, these wreck reefs are now home to a wide variety of fish and marine organisms.
At the Gangneung Underwater Park, divers can explore multiple wreck sites, including the Stella wreck, the largest in Asia at 2,474 tons; the 800-ton Russian trawler MV-33 wreck, which has become a habitat for diverse marine life; the Star Trek wreck, where wrecks and artificial reefs combine to create an even more impressive dive site; a 500-ton refrigerated vessel broken in half by a typhoon; and the “Wreck Village” point, where three 300-ton trawlers are grouped together.
Additionally, the offshore waters of Gangneung, influenced by the ridges of Seoraksan Mountain and Daegwallyeong, feature numerous underwater rock cliffs. Among them are the “Jurassic World”-like rock formations that preserve a sense of primordial mystery. These uniquely shaped rocks, formed by volcanic activity, create an underwater sculpture park.
There is also a dramatic vertical cliff known as the “folding screen” point, as well as a 15-meter-long rock cave where cave diving can be safely enjoyed.
All diving activities at Marine Planet are conducted only at safe points equipped with guide supervision and installed lines, ensuring a secure and enjoyable experience for all participants.
