Jeju Island: A Journey Through South Korea's Natural Wonders

Imagine an island where lush green mountains rise from the sea, where volcanic landscapes meet sprawling beaches, and where every corner reveals a piece of history and a touch of mystique. This is Jeju Island, South Korea’s crown jewel—a destination that offers a blend of natural beauty, cultural heritage, and unique experiences. My adventure on Jeju was a tapestry of awe-inspiring landscapes, warm local encounters, and moments of serene reflection that will remain with me forever. In this article, I’ll share my personal journey through Jeju Island, including must-see attractions, where to eat, where to stay, and insider tips to help you make the most of your visit to this enchanting island.

How to Get to Jeju Island: Your Journey Begins

Getting to Jeju Island is part of the adventure and can be as seamless as it is exciting. I opted for a quick and convenient flight from Seoul’s Gimpo Airport, which takes about an hour and offers breathtaking views of the Korean Peninsula and the sparkling waters of the East China Sea as you approach the island. If you're coming from abroad, Jeju International Airport has direct flights from several major cities in Asia, making it easily accessible. For those who prefer a more leisurely approach, ferries depart from various ports on the mainland, including Busan and Mokpo, providing a scenic entry to the island. The ferry ride offers a unique perspective of Jeju’s rugged coastline and is a great option if you’re looking to bring a car for your island explorations. No matter how you arrive, the moment you step onto Jeju’s shores, you’ll feel the world slow down, welcoming you to an island where nature, culture, and adventure await at every turn.

Arriving on Jeju Island: A Gateway to Serenity

Reaching Jeju Island is the beginning of the adventure, offering a journey that’s both smooth and exhilarating. Whether you fly directly from Seoul or take a ferry from the mainland, the transition from urban life to island serenity is palpable. As I approached Jeju’s coastline, the first thing that struck me was the island’s dramatic landscape—rolling green hills, dark volcanic rock, and the ever-present silhouette of Hallasan Mountain dominating the horizon.

Jeju’s size is deceiving. Though it’s South Korea’s largest island, its diverse terrain and rich cultural sites make it feel like a world unto itself. Renting a car is essential for exploring Jeju, giving you the freedom to discover its hidden gems and secluded spots at your own pace. The roads are well-maintained, but be prepared for some winding mountain routes, especially if you venture into the island’s interior.

How Long to Stay on Jeju Island

To truly experience the best of Jeju, I recommend spending at least five to six days on the island. This will give you ample time to explore its varied landscapes—from volcanic craters to pristine beaches—and immerse yourself in the local culture. A week on Jeju is perfect for those who want to fully unwind and soak up the island’s relaxed atmosphere.

Must-Do Activities on Jeju Island

Jeju Island is a paradise for nature lovers, history buffs, and adventure seekers alike. Here are the highlights of my journey, which made my time on Jeju unforgettable.

1. Hallasan Mountain: Conquering Jeju's Highest Peak

Standing at 1,947 meters (6,388 feet), Hallasan Mountain is the tallest mountain in South Korea and a must-visit for any traveler to Jeju. The hike to the summit is challenging but incredibly rewarding, offering panoramic views of the island and the crater lake, Baengnokdam, at the top.

I set out early in the morning, choosing the Seongpanak Trail, which is one of the most popular routes to the summit. The trail winds through dense forests, volcanic landscapes, and offers glimpses of wildlife along the way. Reaching the summit was a moment of pure triumph, with the view from the top stretching out to the endless sea on one side and the island’s rolling hills on the other.

If you’re not up for the full hike, there are shorter trails that offer beautiful views and a taste of Jeju’s unique flora and fauna. Whichever path you choose, Hallasan is an experience not to be missed.

2. Seongsan Ilchulbong (Sunrise Peak): A Natural Wonder

Seongsan Ilchulbong, also known as Sunrise Peak, is one of Jeju’s most iconic landmarks. This tuff cone, formed by volcanic eruptions over 100,000 years ago, is famous for its stunning sunrise views. I woke up before dawn to make the climb, and the effort was well worth it.

The ascent is relatively easy, taking about 20 minutes along a well-maintained path. As I reached the top, the first rays of the sun began to light up the crater, casting a golden glow over the surrounding sea and cliffs. It was a moment of quiet beauty that I’ll never forget.

Seongsan Ilchulbong is also home to Haenyeo, the legendary female divers of Jeju. Watching these women, who dive without oxygen tanks to harvest seafood, was a humbling experience that connected me to the island’s rich cultural heritage.

3. Manjanggul Cave: Exploring the Depths of a Lava Tunnel

Jeju is renowned for its volcanic landscapes, and Manjanggul Cave is one of the best places to experience this up close. This massive lava tube stretches for over 13 kilometers (8 miles), though only a portion is open to the public.

Walking through the cave felt like stepping into another world—one shaped by the primal forces of nature. The cool, damp air and the eerie silence added to the sense of awe as I explored the tunnel, which features stunning formations like lava stalactites and stalagmites. The highlight of the cave is the 7.6-meter-high (25 feet) lava column, one of the largest in the world.

4. Jeju’s Waterfalls: Nature's Cascading Beauty

Jeju is home to several breathtaking waterfalls, each with its own unique charm. I visited three during my stay: Cheonjiyeon, Jeongbang, and Cheonjeyeon Falls.

Cheonjiyeon Falls is easily accessible and surrounded by lush vegetation, making it a popular spot for a leisurely stroll. Jeongbang Falls is unique in that it’s one of the few waterfalls in Asia that flows directly into the ocean. Standing on the rocky shore, with the spray from the falls mingling with the sea breeze, was a refreshing and invigorating experience.

Cheonjeyeon Falls, known as the “Pond of the Gods,” is a series of three cascades set amidst a serene forest. The legend of nymphs bathing in the waters here adds a touch of mysticism to the site, making it a magical place to visit.

5. Udo Island: A Tranquil Escape

A short ferry ride from Jeju’s eastern coast takes you to Udo Island, a smaller, quieter version of Jeju that’s perfect for a day trip. Udo is known for its white coral beaches, crystal-clear waters, and laid-back vibe.

I rented a bike to explore the island, stopping frequently to take in the stunning coastal views. The highlight for me was Seobinbaeksa, a beach with soft, white sand and turquoise waters that felt like a slice of paradise. Udo is also famous for its peanut ice cream—a must-try treat after a day of exploring.

6. Jeju Olle Trail: A Hiker’s Paradise

The Jeju Olle Trail is a network of 26 walking paths that wind their way around the island, covering a total of 425 kilometers (264 miles). Each trail offers a unique perspective of Jeju’s diverse landscapes, from coastal cliffs to rural villages and volcanic craters.

I chose to hike a portion of Trail 7, which runs along the southern coast of the island. The path took me through scenic coastal views, past hidden beaches, and along dramatic cliffs. The highlight was the walk through the Seogwipo Forest of Healing, where the lush greenery and the sound of the waves created a truly peaceful atmosphere.

Whether you’re an avid hiker or just looking for a leisurely stroll, the Olle Trails offer something for everyone. Each trail is well-marked, and many pass through small villages where you can stop for a snack or drink and interact with locals.

7. Spirited Garden: A Zen Oasis

Tucked away in the heart of Jeju is the Spirited Garden, one of the most serene and beautifully curated botanical gardens I’ve ever visited. This tranquil oasis is known for its impressive collection of bonsai trees, some of which are over 300 years old, as well as its calming water features and meticulously maintained landscapes.

I spent a peaceful afternoon wandering through the garden’s seven themed sections, each designed to reflect harmony with nature. The Spirited Garden also offers a small tea house where you can enjoy a cup of traditional Korean tea while overlooking the serene scenery.

The garden’s founder, Bum-Young Sung, began cultivating the garden in the 1960s, transforming a barren wasteland into this lush paradise. His philosophy of patience and dedication is evident in every corner of the garden, making it a place where you can slow down, reflect, and connect with nature.

8. Dongbaekdongsan Wetland: A Birdwatcher’s Delight

For nature enthusiasts, the Dongbaekdongsan Wetland is a hidden gem on Jeju Island. Located near the northeastern coast, this protected wetland area is a haven for birdwatchers and those looking to explore Jeju’s unique ecosystems.

I visited early in the morning to catch the best of the bird activity. The wetland is home to a variety of migratory birds, including the endangered black-faced spoonbill. As I quietly walked along the boardwalks that crisscross the wetland, I spotted several species of waterfowl and songbirds, all against the backdrop of a misty, tranquil landscape.

Dongbaekdongsan is also home to a dense forest of camellia trees, which bloom in vibrant red during the winter months. The combination of wetland and forest creates a rich environment for wildlife, making it a must-visit for anyone interested in Jeju’s natural beauty and biodiversity.

Before you set off on your Jeju adventure, here are a few tips that made my time on the island even more enjoyable:

Timing: Jeju is beautiful year-round, but the spring and fall offer the most pleasant weather, with fewer tourists. Cherry blossom season in April and the autumn foliage in October are particularly stunning.
