Welcome to Jeju Island: South Korea’s Volcanic Gem

I went to South Korea and Jeju Island on a scientific conference in 2015. And I loved Jeju so much that I extended my stay to explore more. Jeju Island is where nature whispers, the wind sings, and everything feels just a little more alive.

Often called “the Hawaii of Korea,” Jeju is a volcanic island full of lush trails, lava caves, dramatic coastlines, quirky museums, and tangerine trees as far as the eye can see. It’s where Korean honeymooners go to celebrate love, hikers go to challenge themselves, and weary travelers go to breathe. Jeju is more than just beautiful — it’s soulful. From the haenyeo (the island’s legendary free-diving grandmothers) to ancient stone statues and windswept fields, the island carries a sense of quiet resilience and tradition. It's peaceful, powerful, and just unpredictable enough to keep things interesting.

There’s something special about the cozy, smoky atmosphere in Jeju’s tiny restaurants, where you grill your own meat at the table — especially the island’s famous black pork, wrapped in fresh greens with a kick of spicy kimchi. Whether you're looking for a spiritual retreat, a seaside hike, or just a really good tangerine, Jeju has something for you.

There is a lot to see and do in Jeju Island. Here is a collection of some fun stuff. And don´t forget to see the superwomen Haenyeo dive and try their fresh seafood. This tradition is also featured in the new K-drama “When life gives you tangerines” on Netflix.

What to See and Do on Jeju Island

1. Hike Hallasan Mountain
Climb South Korea’s highest peak, right in the center of the island. The trail is demanding, but the views are unforgettable.

2. Visit Seongsan Ilchulbong (Sunrise Peak)
This dramatic volcanic crater is one of Jeju’s most iconic sights. It's especially magical at sunrise — if you’re willing to make the early climb.

3. Watch the Haenyeo in Action
These elderly women dive without oxygen tanks to collect seafood from the ocean floor. Visit the Haenyeo Museum or catch a live demonstration along the coast.

4. Walk the Jeju Olle Trails
A network of coastal paths that stretch around the island. Ideal for slow travel, scenic views, and discovering small villages along the way.

5. Relax in a Jjimjilbang (Korean Spa)
After a windy day of exploring, soak in mineral-rich baths and enjoy a full-body scrub like the locals do.

6. Explore Manjanggul Lava Tube
Step into one of the world’s longest lava tunnels — a dark, cool, and fascinating journey into Jeju’s volcanic past.

7. Visit Yongduam Rock (Dragon Head Rock)
A wind-beaten coastal formation shaped like a dragon, wrapped in local legend and great photo ops.

8. Eat Jeju Tangerines
Sweet, juicy, and everywhere. Try them fresh, dried, juiced, or even in chocolate. They're part of the island's identity.

9. Discover Jeju’s Quirky Museums
From teddy bears and tea to erotic sculpture, Jeju has a museum for every mood and sense of humor.

10. Unwind at Hyeopjae Beach
White sand, clear turquoise water, and peaceful surroundings make this one of Jeju’s best spots to relax.
