Top Things to Do
Sunrise Hike up Seongsan Ilchulbong
Ascend the 'Sunrise Peak' before dawn to witness a truly magical spectacle as the sun paints the sky in vibrant hues over the vast ocean. The volcanic crater at the summit offers a unique geological wonder, and the climb, while a bit steep, is rewarded with unparalleled panoramic views of Jeju's eastern coast.
Explore the Haenyeo's Underwater World
Witness the incredible bravery and skill of Jeju's 'haenyeo' (female divers) as they harvest seafood without oxygen tanks. While seeing them in action is a privilege, consider visiting a haenyeo museum or a local restaurant serving their fresh catch for an authentic taste of their livelihood.
Wander Through the Camellia Gardens of Dongbaek
Lose yourself in the enchanting beauty of the Camellia Arboretum, especially during its peak bloom. Stroll along winding paths surrounded by thousands of camellia trees, their vibrant red and pink blossoms creating a breathtaking natural tapestry. It's a photographer's paradise and a tranquil escape from the bustling tourist spots.
Savor Black Pork BBQ at a Local 'Gogi-jip'
Indulge in Jeju's famous black pork, renowned for its rich flavor and tender texture. Find a bustling, no-frills 'gogi-jip' (meat house) where locals gather, grill the succulent pork belly over charcoal, and wrap it in fresh lettuce with garlic and kimchi for an unforgettable culinary experience.

Essential Travel Tips
Rent a car if you want to truly explore Jeju's hidden gems beyond the main tourist routes. While buses are available, they can be infrequent and time-consuming, especially for reaching scenic spots like the east coast's Seongsan Ilchulbong or the south's Jeongbang Waterfall. Having your own wheels gives you the freedom to stop whenever a breathtaking view catches your eye.
Don't leave Jeju without trying the black pork (Heuk-dwaeji) and fresh seafood, especially abalone. Many restaurants in areas like Seogwipo offer 'heukdwaeji' set menus where you grill the succulent pork yourself at the table. For seafood, head to a local market like Dongmun Market and pick out your own fish to be prepared at a nearby restaurant for a truly authentic and delicious experience.
Be mindful of the 'Haenyeo' (female divers) and their traditions; they are a UNESCO Intangible Cultural Heritage. If you see them harvesting seafood, observe respectfully from a distance and avoid disturbing them. Some areas offer opportunities to watch their demonstrations or even try their freshly caught seafood, which is a unique cultural immersion.
While credit cards are widely accepted, carrying some cash is a good idea for smaller, local establishments or street food vendors, especially in more rural areas. You can easily withdraw Korean Won (KRW) from ATMs at the airport or in most towns. Having a bit of cash on hand ensures you won't miss out on delicious snacks or unique souvenirs from smaller shops.
Pack layers, as Jeju's weather can change rapidly, especially between seasons. Even in summer, evenings can be cool, and coastal winds can be strong. A waterproof jacket and comfortable walking shoes are essential for exploring the island's diverse landscapes, from volcanic craters to coastal trails.
Jeju is generally very safe, but be aware of natural hazards when hiking. Trails like Hallasan can be challenging, and conditions can change quickly. Always check the weather forecast before heading out, inform someone of your hiking plans, and carry water and snacks. Stick to marked paths to avoid getting lost.
💡 Travel Tip: If you're planning your trip, it's worth checking flight prices on Trip.com before you decide.

Frequently Asked Questions
When is the absolute best time to visit Jeju Island, and what should I pack for it?
Honestly, spring (April-May) and autumn (September-October) are magical on Jeju. Spring bursts with vibrant azaleas and cherry blossoms, while autumn offers crisp air and stunning foliage. Pack layers! Even in these pleasant seasons, the wind can pick up, especially near the coast, so a light jacket or sweater is a must. Comfortable walking shoes are non-negotiable, as you'll want to explore those volcanic trails and coastal paths.
I'm not fluent in Korean. How will I get around Jeju Island without a car?
Don't worry, Jeju is surprisingly navigable for non-Korean speakers! The intercity bus system is quite efficient and covers most major attractions, with signage often having English translations. For more flexibility, consider using Kakao Taxi, South Korea's equivalent of Uber, which is very user-friendly and has an English option.

For a truly peaceful experience, head to the west coast and explore the 'Aewol Handam Coastal Trail' early in the morning before the cafes get busy.

If you're up for a bit of a hike, the less-trafficked trails around 'Hallasan National Park' offer stunning views without the throngs you'll find on the main routes.
