Best Things to Do on Jeju Island
Climb the Volcanic Crater of Seongsan Ilchulbong
One of the most iconic landmarks on Jeju Island, Seongsan Ilchulbong—also known as Sunrise Peak—rises dramatically from the sea on the island’s eastern coast. Formed by a volcanic eruption thousands of years ago, the crater resembles a massive fortress of rock surrounded by grassy slopes.
Visitors can climb a well-maintained path to the top of the crater, where panoramic views reveal the surrounding coastline and countryside. The hike takes about 20–30 minutes and rewards travelers with one of the most spectacular viewpoints on the island.
Sunrise is especially popular here, when the first rays of light illuminate the volcanic crater and the ocean beyond.
The volcanic landscapes of Jeju are protected in several natural areas across the island. Travelers interested in hiking may also enjoy exploring the best national parks in South Korea.
Hike the Slopes of Hallasan
Dominating the center of Jeju Island, Hallasan is the tallest mountain in South Korea and the centerpiece of Hallasan National Park. The dormant volcano rises nearly 2,000 meters above sea level and offers some of the best hiking in the country.
Several trails lead through forests, alpine meadows, and volcanic landscapes toward the summit. At the top lies Baekrokdam, a crater lake surrounded by dramatic mountain scenery.
Hiking Hallasan provides a unique opportunity to experience Jeju’s diverse ecosystems and breathtaking natural beauty.
Hallasan is the highest mountain in South Korea and part of Hallasan National Park, one of the country’s most spectacular hiking destinations.
Explore the Underground World of Manjanggul Lava Tube
One of the most fascinating geological sites on Jeju Island is Manjanggul Lava Tube, a massive underground tunnel formed by flowing lava thousands of years ago.
Stretching more than 13 kilometers in total length, Manjanggul is one of the longest lava tunnels in the world. Visitors can explore a section of the cave featuring enormous lava formations, stalactites, and dramatic stone columns created by ancient volcanic activity.
Walking through the cool, dimly lit tunnel offers a glimpse into the island’s volcanic origins.
Visit the Oceanfront Jeongbang Waterfall
Unlike most waterfalls, Jeongbang Waterfall flows directly into the sea. Located near Seogwipo, the waterfall plunges from a cliff into the rocky shoreline below.
Visitors can walk down a path leading to the base of the falls, where the powerful cascade crashes into the ocean. The surrounding coastal scenery creates one of the most dramatic natural landscapes on Jeju Island.
Discover the Beauty of Cheonjiyeon Waterfall
Another beautiful waterfall near Seogwipo is Cheonjiyeon Waterfall, surrounded by lush forest and scenic walking paths. The name translates to “sky connected with land,” reflecting the graceful appearance of the cascading water.
The peaceful surroundings make Cheonjiyeon a popular place for evening walks, especially when the path to the waterfall is illuminated at night.
Admire the Coastal Views at Seopjikoji
On the eastern side of the island, Seopjikoji offers sweeping coastal scenery with dramatic cliffs, grassy fields, and panoramic ocean views.
Walking trails lead across the headland toward a small lighthouse overlooking the sea. The area is especially beautiful during spring when yellow canola flowers bloom across the landscape.
Take a Ferry to Udo Island
Just off the eastern coast of Jeju lies the small island of Udo, a peaceful destination known for its scenic beaches and rural atmosphere.
Visitors can reach Udo by ferry and spend the day cycling or driving around the island while enjoying coastal views and quiet fishing villages.
See the Volcanic Formations of Jusangjeolli Cliffs
Along the southern coast of Jeju Island, the Jusangjeolli Cliffs display impressive hexagonal stone columns formed by cooling lava. The geometric rock formations rise dramatically above the ocean and create a fascinating natural landscape.
Waves crashing against the cliffs add to the dramatic scenery, making this one of the island’s most striking viewpoints.
Best Beaches on Jeju Island
Jeju Island is also home to several beautiful beaches. Among the most popular are Hyeopjae Beach, known for its clear turquoise water, and Jungmun Beach, a scenic stretch of sand surrounded by dramatic cliffs.
These beaches offer opportunities for swimming, relaxing, and enjoying the island’s coastal scenery.
