Jeju Island (제주도) is South Korea’s tropical paradise — a UNESCO World Heritage volcanic island that attracts 15 million visitors annually. Located off the southern coast of the Korean peninsula, Jeju offers a dramatic landscape of volcanic craters, lava tubes, pristine beaches, and lush countryside that feels a world away from Seoul’s urban energy. In 2026, new luxury resorts, improved infrastructure, and year-round direct flights from 30+ international cities make Jeju more accessible than ever.
Why Jeju Island Should Be on Your List

Jeju is often called “Korea’s Hawaii,” but it has a character entirely its own. The island is home to Hallasan, South Korea’s highest peak (1,950m), a dormant volcano with a stunning crater lake at its summit. Hundreds of secondary volcanic cones (오름, oreum) dot the landscape, creating a rolling green terrain unlike anywhere else in Korea.
The island also boasts a unique culture distinct from mainland Korea. The famous haenyeo (해녀) — female divers who harvest seafood without oxygen tanks — are a UNESCO-recognized cultural heritage. Jeju’s dialect is so different from standard Korean that mainlanders often cannot understand it. And the ubiquitous dol hareubang (돌하르방) stone statues have become one of Korea’s most recognizable cultural symbols.
Top Experiences in Jeju
1. Hallasan National Park
Climbing Hallasan is the ultimate Jeju experience. The Seongpanak trail (9.6 km one way) is the most popular route, taking approximately 4-5 hours to reach the summit. On clear days, the view from Baengnokdam crater lake is breathtaking — you can see the ocean in every direction. Start early (before 6 AM) to ensure you reach the summit before the noon cutoff time.
2. Manjanggul Lava Tube
One of the longest lava tubes in the world at 7.4 km (1 km is open to visitors). Walking through this natural underground tunnel, formed by volcanic lava flows thousands of years ago, is an awe-inspiring experience. The tube maintains a constant cool temperature, making it perfect for hot summer days.
3. Seongsan Ilchulbong (Sunrise Peak)
A dramatic volcanic crater rising from the ocean on Jeju’s eastern tip. The sunrise hike takes about 25 minutes and rewards you with one of the most spectacular views in Korea. At the base, you can watch the haenyeo divers perform their daily harvest and buy fresh seafood on the spot.
4. Jeju Olle Trail
A network of 26 walking routes (totaling 425 km) that circle the entire island along the coastline. Each route takes 5-8 hours and showcases different landscapes — from black volcanic beaches to green tea plantations to clifftop ocean paths. Route 7 (Wolpyeong to Jungmun) is considered the most scenic.
5. Jeju Food Scene
Jeju’s food culture centers on fresh seafood and unique local specialties. Black pork (흑돼지, heukdwaeji) raised on the island has a distinctive rich flavor. Abalone porridge (전복죽, jeonbok-juk) is a must-try breakfast. And the island’s tangerines (감귤, gamgyul) are famous throughout Korea — you will find them in everything from juice to chocolate to skincare products.
- Black Pork Street (Heukdwaeji Street): A whole street in Jeju City dedicated to grilled black pork restaurants.
- Dongmun Market: The best market for fresh seafood, including live abalone, sea urchin, and grilled shellfish.
- Jeju Tangerine Farms: Visit from October to February to pick your own tangerines.

Whether you come for the hiking, the food, the beaches, or simply to escape the city, Jeju delivers an unforgettable Korean travel experience.
