East Jeju: Crater, the cave and the labyrinth

Manjanggul – an epic tunnel formed by molten lava millions of years ago.

Its length stretches an impressive 8.928 kilometers, with a width of up to 23 meters and a height of 30 meters. Manjanggul proudly ranks as the 12th longest lava tube on Earth and the 2nd longest on Jeju Island. However, only a portion of the cave is open to visitors.

This geological masterpiece is part of the renowned Geomunoreum Lava Tube System, listed as a UNESCO World Heritage Site. It is home to a 7.6-meter-high lava column—the largest ever discovered on planet Earth—alongside magnificent lava stalactites, stalagmites, and shelves.

But that’s not all! Manjanggul is not only a monument to geology but also a habitat for fascinating creatures. It hosts the enigmatic Jeju cave-spider and Korea’s largest colony of bent-wing bats, numbering over 30,000 individuals.

In short, Manjanggul is a must-visit destination for anyone fascinated by volcanic artistry, biodiversity, or the thrill of walking through Earth’s ancient fiery veins.

Seongsan Ilchulbong (Korean: 성산일출봉), also known as Sunrise Peak, is a stunning volcanic formation located on the eastern side of Jeju Island. Rising to a height of 182 meters, this natural wonder features a volcanic crater at its summit, offering breathtaking views of the island's landscapes.

Seongsan Ilchulbong is part of the UNESCO World Heritage Site listing under Jeju Island and its lava tubes, recognized for its geological and scenic significance. A visit to this magnificent peak promises an unforgettable encounter with Jeju's natural beauty.

Kimnyeong Maze Park (Korean: 김녕미로공원) is a charming maze park located in Jeju City.

The maze impresses with its scale and beauty. The hedges are formed from evergreen trees that remain lush and green throughout the year. The unique scent of these trees, combined with the volcanic basalt stones paving the park's paths, creates a refreshing atmosphere that energizes travelers as they navigate the winding routes of the maze.

This park is popular among people of all ages and is especially beloved by families. It is not only an excellent destination for couples, children, and adults but is also recognized as one of the most cherished spots among Jeju residents.
