Jeju is South Korea's volcanic island getaway, a UNESCO-recognized land of lava tubes, crater peaks, black-sand beaches and emerald coves rising off the country's southern tip. Born from eruptions that shaped Hallasan, the nation's highest mountain, the island rewards every kind of traveler: hike a sunrise crater on the east coast, wander basalt waterfalls in the south, watch free-diving haenyeo grandmothers surface with the day's catch, or simply trace coastal Olle trails between fishing villages. Here are the best things to do in Jeju, from its most iconic landmarks to the quiet corners locals love.
🏯 Top Attractions in Jeju
⛰️
Seongsan Ilchulbong (Sunrise Peak)
성산일출봉
This dramatic tuff cone rose from an undersea volcanic eruption, forming a vast green crater rimmed by jagged rocks on Jeju's eastern coast. A steep stairway climbs to the summit, famous for spectacular sunrises over the sea, and it is part of the island's UNESCO World Heritage listing.
⛰️
Hallasan National Park
한라산국립공원
At the heart of the island stands Hallasan, a dormant shield volcano and South Korea's tallest mountain, crowned by the Baengnokdam crater lake. Several well-marked trails wind through changing forests to alpine meadows, with the Seongpanak and Gwaneumsa routes reaching the summit.
📍
Manjanggul Lava Tube
만장굴
One of the world's finest lava tubes, this cavern was carved by molten rock flowing from a Geomunoreum eruption thousands of years ago. A walkable section reveals lava stalactites, rope-like flow walls and a towering lava column, all part of Jeju's UNESCO natural heritage.
💧
Cheonjeyeon Waterfall
천제연폭포
A three-tier cascade in Seogwipo plunges through a lush subtropical gorge ringed by rare plants and ferns. The arched Seonimgyo Bridge, decorated with carvings of mythical nymphs, spans the ravine and links the falls to a scenic riverside walk.
💧
Jeongbang Waterfall
정방폭포
Said to be one of the few waterfalls in Asia that tumbles directly into the ocean, Jeongbang spills off a coastal cliff onto the rocks below. The sound of crashing water meeting the sea makes it a memorable stop along Seogwipo's southern shore.
🏝️
Udo Island
우도
A short ferry ride off the eastern coast, this small island is named for its cow-lying shape and circled by easy bike, scooter and walking routes. Highlights include a rare coral-sand beach, low stone walls, lighthouses and views back toward Sunrise Peak.
🏖️
Hyeopjae Beach
협재해수욕장
On the northwest coast, Hyeopjae draws crowds with its powdery white sand, shallow turquoise water and views of the cone-shaped Biyangdo island offshore. A grove of pine trees backs the shore, and the adjoining Geumneung Beach extends the same scenery.
🏝️
Jeju Olle Trails
제주올레길
This network of waymarked walking routes loops around the island, linking coastline, oreum volcanic cones, villages and forests over more than two dozen numbered courses. Blue-and-orange ribbons mark the way, letting walkers sample Jeju at a slow, scenic pace.
📍
Camellia Hill
카멜리아힐
A sprawling botanical garden in the island's west planted with hundreds of camellia varieties alongside seasonal blooms and themed walking paths. It is especially loved in the cooler months when the camellias flower, making it a favorite for photographers.
📍
Seopjikoji
섭지코지
A grassy cape jutting into the sea near Sunrise Peak, Seopjikoji is known for its lighthouse, wildflower fields and sweeping coastal views. The headland's volcanic rock formations and breezy walking paths have made it a popular filming location.
🍜 What to Eat in Jeju
🍖
Heukdwaeji (Jeju black pork)
Jeju's prized native black pigs yield rich, flavorful pork grilled over charcoal at barbecue restaurants island-wide. It is the island's signature meat dish, often eaten with salted shrimp sauce and fresh garlic.
🍽️
Galchi (cutlassfish)
Long, silvery hairtail fish are a Jeju specialty served as a hearty braise with radish and chili (galchi-jorim) or simply grilled. The freshest catches come straight from the surrounding seas.
🦞
Jeonbok-juk (abalone porridge)
A comforting rice porridge cooked with tender abalone, often harvested by haenyeo divers, tinted green from the shellfish. It is considered a nourishing, restorative Jeju classic.
🍖
Gogi-guksu (pork noodle soup)
A beloved local comfort food of wheat noodles in a milky pork-bone broth topped with slices of boiled pork. You will find dedicated noodle shops serving it across the island.
🍽️
Hallabong citrus
A sweet, bump-topped mandarin variety grown on Jeju's sunny slopes, named after Hallasan. Look for it fresh as well as in juices, chocolates and other island treats.
🦞
Fresh seafood and sashimi
Surrounded by sea, Jeju is known for ultra-fresh sashimi, sea urchin and shellfish, much of it gathered by haenyeo divers. Coastal markets and harbor restaurants serve the day's catch.
🚄 Getting There & Getting Around
Most travelers reach Jeju by air: Jeju International Airport sits just outside Jeju City on the north coast and is one of the world's busiest routes, with frequent flights from Seoul (Gimpo), Busan and other mainland cities, plus some international connections. Ferries also run to Jeju from mainland ports such as Wando, Mokpo and Busan for those bringing a vehicle or preferring the sea. Once on the island, renting a car is the most flexible way to explore, as many natural attractions are spread along the coast and into the interior; an extensive local and intercity bus network connects Jeju City, Seogwipo and major sights for those not driving.
💡 Insider Tips
Renting a car gives you the most freedom, since top sights are scattered around the coast and mountains and public transport between them can be slow.
Weather changes fast and the island is windy, so pack layers and a rain shell even in summer, and check conditions before a Hallasan summit hike.
Sunrise Peak lives up to its name at dawn, but it is also far less crowded and just as scenic in late afternoon light.
Base yourself strategically: Jeju City in the north suits airport access and nightlife, while Seogwipo in the south is closer to waterfalls and the Jungmun resort area.
Three to four days lets you cover the main highlights at a comfortable pace, splitting time between the east coast (Sunrise Peak, Manjanggul, Udo) and the south and west (waterfalls, beaches, gardens). A week allows for a Hallasan hike, multiple Olle trails and slower island living.
What is the best time of year to visit Jeju?
Spring brings canola and cherry blossoms, while autumn offers crisp, clear weather ideal for hiking, making both the most popular seasons. Summer is warm and busy with beachgoers, and winter is mild compared with the mainland, with camellias in bloom and occasional snow on Hallasan.
Do you need to climb to the summit to enjoy Hallasan?
No. The full summit hike to Baengnokdam crater is long and demanding, but shorter, easier trails through the national park's forests and to viewpoints let you experience the mountain without going all the way up. Summit routes can require advance reservation, so check before you go.
Can you visit Jeju without renting a car?
Yes. Jeju has an extensive bus network linking the airport, Jeju City, Seogwipo and major attractions, and many travelers combine buses with taxis or guided day tours. That said, a rental car makes reaching remote beaches, oreum and trailheads far easier and faster.
