Jeju-do's must-do activities
Jeju Island is packed with natural and cultural attractions that are well worth a visit. Here are the activities you absolutely can't miss on your visit to this island paradise.
Climbing Mount Hallasan
In the heart of Jeju rises proudly Mt. Hallasan (한라산), South Korea's highest point at 1,950 metres. This dormant volcano, listed as a UNESCO World Heritage Siteis an unforgettable hiking experience that all nature lovers should undertake.
Why climb Mount Hallasan? First and foremost for its exceptional panoramic views! At the top, you'll be rewarded with a breathtaking view of the whole island and, on a clear day, you can even see the coast of mainland Korea. The volcanic crater with its lake, named Baengnokdam, offers a breathtaking spectacle that changes with the seasons.
The ascent can be made via several trails of varying difficulty:
- The Gwaneumsa trail (8.7 km): the most direct but also the most demanding
- Seongpanak trail (9.6 km): longer but with a gentler gradient, ideal for beginners
- The Eorimok trail: shorter but does not lead to the summit
- Yeongsil trail: perfect for a shorter hike with magnificent views
Don't forget that the hike takes a full day (allow 8-10 hours round trip). It's essential to set off early in the morning, wearing suitable clothing and carrying sufficient water and provisions. The weather can change rapidly on the mountain, so bring waterproof clothing even if the skies are clear at the start.
Pro tip Please check trail closing times before setting off, as they vary according to the season, and it is not permitted to continue climbing beyond a certain time for safety reasons.
Exploring the Manjanggul Lava Tubes
Another natural wonder not to be missed is Manjanggul Cave (만장굴), one of the world's longest lava tubes at 13.4 km. Only 1 km is open to the public, but that's more than enough to marvel at this geological masterpiece formed some 300,000 years ago.
When you enter this cavern, you'll discover a fascinating subterranean world of lava stalactites, columns and rock formations sculpted by nature. The highlight is undoubtedly the giant 7.6-metre lava column, considered to be the largest in the world.
The temperature inside remains constant at around 11-16°C all year round, making it a particularly refreshing visit on hot summer days. The floor can be slippery and uneven, so wear comfortable shoes with non-slip soles.
How do I get there? The cave is about a 30-minute drive from Jeju-si. Buses run regularly from Jeju's bus station, but renting a car is the most practical option for exploring the island freely.
Relax on the Black and White Sand Beaches
Jeju is surrounded by magnificent beaches that provide idyllic places to relax. Unlike most destinations, the island offers both white sand and volcanic black sand beaches, each with its own unique charm.
Jeju's most beautiful beaches :
- Hyeopjae Beach (협재해변) : Renowned for its pristine white sand and crystal-clear, emerald-hued waters. From the beach, you'll have a splendid view of Biyang Island.
- Hamdeok Beach (함덕해변): Very popular with families for its shallow waters and beautiful turquoise color. Photography enthusiasts will particularly appreciate the bridge that juts out into the sea.
- Jungmun Beach (중문해변): Known for its bigger waves, this is Jeju's favorite surf spot. The sand here is slightly darker and the setting, surrounded by volcanic cliffs, is particularly photogenic.
- Samyang Beach (삼양해변): One of the island's most famous black sand beaches, with therapeutic properties according to the locals. Walking barefoot on this sand is considered beneficial to health.
During the summer months (July-August), the beaches are equipped with showers and changing rooms, and offer water sports activities such as jet-skiing, banana boating and snorkeling. The rest of the year, they offer a more peaceful atmosphere, perfect for long, contemplative walks.
Good to know : If you're visiting Jeju during the summer season, choose early morning or late afternoon to avoid the crowds, especially on the most popular beaches like Hyeopjae.
Visit Cheonjeyeon Waterfall
The Cheonjeyeon waterfalls (천제연폭포), nicknamed "the pond of the gods", are among Jeju's most enchanting natural attractions. The site actually comprises three separate waterfalls, each flowing into a deep-blue pool.
Legend has it that nymphs descended from the sky to bathe in these pure waters. This story inspired the spectacular "Seonimgyo" bridge that spans the waterfalls, adorned with seven sculpted nymphs who seem to watch over the area.
The site is beautifully landscaped, with wooden paths winding through lush vegetation. The walk is relatively easy and accessible to all. The contrast between black volcanic rock and lush green vegetation creates an almost mystical atmosphere, especially at the end of the day.
For an even more complete experience, don't miss the "Jeju Sori" night show sometimes held near the waterfalls, featuring local mythology with sound and light.
Discover the Seongeup Folk Village
To immerse yourself in Jeju's history and traditions, there's nothing like a visit to the Seongeup folk village (성읍민속마을). This well-preserved, traditional village offers an insight into how the island's inhabitants lived before modernization.
As you stroll through the narrow streets lined with volcanic stone walls, you'll see thatched-roof houses, altars dedicated to local deities and "dolhareubang" (stone statues symbolic of Jeju). The inhabitants continue to live a traditional lifestyle, cultivating the land and perpetuating local crafts.
Be sure to visit one of the houses open to the public to admire the typical architecture with its "ondol" (underfloor heating system) and living spaces adapted to the island's sometimes harsh climate.
The village also offers demonstrations of traditional crafts and sometimes folk music and dance performances. It's the ideal place to buy authentic souvenirs such as Jeju barley tea or volcanic stone objects.
Insider tip: For a truly immersive experience, some traditional houses offer overnight stays or more, allowing you to live like the locals and sample authentic Jeju cuisine.

The highlight of the show is the 23-metre transparent tunnel where you can walk among sharks, rays and other impressive sea creatures. Dolphin and sea lion shows are scheduled several times a day, enchanting young and old alike.
The aquarium also showcases the unique marine ecosystem that surrounds Jeju, allowing you to discover endemic species that you might spot diving around the island if the weather improves.
Relax in a traditional Korean spa
What could be better than a rainy day for a moment of pure relaxation? Jeju has several traditional Korean spas (jjimjilbang) that offer an authentic wellness experience.
The most recommended is Spa World in Jungmun, which combines thermal baths, saunas at different temperatures and relaxation rooms. Some establishments use seawater or local ingredients such as Jeju citrus fruits for their treatments.
For a truly local experience, try heugimja (black sesame seed) or seaweed baths, renowned for their skin-care benefits.
Good to know In traditional Korean spas, bathing areas are generally separated by gender, and nudity is the rule. Prepare yourself for this cultural peculiarity, or find out which establishments offer alternatives.

Organization Council This itinerary assumes you have a rental car, which is the most practical option for exploring Jeju. If you depend on public transport, you may need to adjust the program according to bus schedules.
What to do in Jeju without a car: Getting around with local transport
Although renting a car is the most convenient way to explore Jeju, it's entirely possible to enjoy the island without a personal vehicle. Here's how to navigate efficiently using local transport.
Using Jeju's bus network
Jeju's bus network has improved considerably in recent years, making it a viable option for travelers. There are two main types of bus:
- Express buses (numbers 100 to 900): connecting the main towns and attractions with few intermediate stops. The 181 bus is particularly useful as it circles the island, passing many tourist sites.
- Local buses (numbers above 1000): They serve more remote areas but with less frequent passages.
The " Jeju Bus Information "(available in English) is indispensable for planning your trips, as it provides real-time timetables and itineraries.
To simplify your travels, consider purchasing a T-MoneyIt's refillable and can be used on all buses. It saves you having to prepare the exact change for each journey.
Practical tip Bus schedules: Please note that bus schedules are less frequent in the evening and that some lines stop operating relatively early. Plan your return journey accordingly to avoid getting stuck.
Opt for sightseeing bus tours
For those who prefer a more organized solution, sightseeing bus tours are an excellent alternative. The "Jeju Golden Bus" company offers several itineraries covering the island's main attractions. Advantages of these tours:- No planning or navigation worries
- Stops at major attractions with plenty of time to explore
- Reasonable prices (between 40,000 and 70,000 won depending on the itinerary)
These tours are generally divided into three routes: East, West and South, allowing you to cover the whole island in three days.
Combining bus and electric bike
An interesting hybrid option is to use buses for longer distances and rent an electric bike to explore the area around your arrival point. Many rental centers offer electric bikes by the day (around 20,000 to 30,000 won).
This solution is particularly suitable for exploring the coast or specific areas such as the Olle coastal path, which circles the island over 400 km divided into 21 sections.
Staying strategically
Without a car, your choice of accommodation becomes even more strategic. Choose areas with good public transport links:
- Jeju-si (main city): Central point for buses in all directions
- Seogwipo : Well-connected and close to many southern attractions
- Jungmun Tourist area with many attractions within walking distance
By staying in these areas, you can easily reach certain attractions on foot, and enjoy good bus connections for excursions further afield.
Conclusion: Make your trip to Jeju an unforgettable experience
Jeju Island is truly a South Korean treasure worth exploring in depth. Whether you're attracted by its natural wonders, rich culture or simply relaxing on its idyllic beaches, what to do in Jeju will never again be a perplexing question.
The beauty of this destination lies in its diversity: in a single day, you can climb a volcano, explore prehistoric caves, relax on a white sandy beach and enjoy seafood freshly caught by the haenyeo. Few destinations in the world offer such a variety of experiences in such a compact space.
Don't forget that, whatever the season of your visit, Jeju always has something to offer: cherry blossoms in spring, lively beaches in summer, blazing foliage in autumn and tranquil camellia-covered landscapes in winter.
