• Yeongsil Trail: Scenic, forested, with waterfalls and lava formations. Best time to visit is Autumn

Tips:

• Check trail conditions, especially in winter (November–February) – ice and snow can make some paths treacherous
• Arrive early for sunrise views and avoid afternoon crowds
• Bring plenty of water, snacks, and layers to keep warm

Did You Know?: Hallasan isn’t just a hike – it’s a living ecosystem with endemic plants and wildlife that’s unique to Jeju. The park is managed by Korea National Park Service, so the trails are safe, easy to follow and well-maintained.

Jeju Waterfalls

Jeju is home to some of Korea’s most picturesque waterfalls. Most of the main waterfalls are easy to access and family-friendly.

Top Picks:

• Cheonjiyeon Waterfall (Seogwipo): 22 meters tall, illuminated at night. Accessible via a paved path
• Jeongbang Waterfall: The only waterfall in Asia that falls directly into the ocean
• Cheonjeyeon Waterfall: Three-tiered waterfall surrounded by lush forest and small bridges

Tips:

• Early mornings are quieter – ideal for capturing photos free from other tourists
• Wear waterproof shoes (with good grip) if you plan to walk near the base of the falls

Did You Know?: These waterfalls are part of Jeju’s volcanic landscape, shaped over millennia. Visiting them offers both natural beauty and a window into the island’s geological history.

Lava Tubes

Jeju’s underground caves are a UNESCO World Heritage site and offer a glimpse of the island’s volcanic past.

Must-Visit:

• Manjanggul Cave: One of the longest lava tubes in the world. Walking trail is 1 km of a total 13 km cave
• Gimnyeong Lava Tube: Smaller, easier to navigate, with stalactites and stalagmites

Tips:

• Bring a light jacket – even if it’s hot outside the caves are cool year-round and often drip water from the roof of the cave
• Wear comfortable shoes with good grip
• Photography is allowed, but using a flash may be restricted in some areas (check signage)

Did You Know?: Lava tubes are geologically significant formations. They provide scientists with clues about Jeju’s volcanic activity. Manjanggul is protected under UNESCO regulations.

Jeju Beaches

Jeju’s beaches vary from calm, family-friendly shores to dramatic coastal cliffs.

Top Beaches:

• Hyeopjae Beach (West): White sand, clear turquoise waters, lots of nearby cafés
• Hamdeok Beach (Northeast): Shallow waters perfect for kids, calm tides and plenty of space for running around
• Woljeongri Beach: Less crowded, soft sand, peaceful surroundings (with plenty of cafés offering great views)

Tips:

• Summer (July–August) is peak swimming season but means the beaches are crowded – and also full of Korean lifeguards who can be overly zealous with safety!
• Winter offers dramatic coastlines for photos, but the water is too cold for swimming (unless you’re REALLY brave)
• Check tidal charts if you’re planning water activities

Did You Know?: Jeju’s beaches are shaped by volcanic activity, resulting in unique black sand beaches in some areas like Samyang.

Walks and Trails

Jeju has a huge network of coastal paths, forest walks, and mountain trails which makes it a great destination if you love spending time outdoors walking. This also includes parts of the famous Olle Trails.

Recommended Walks:

• Olle Trail 1-1 (Seongsan to Udo): Coastal cliffs, farmland, and small fishing villages
• Saryeoni Forest Path (Hallasan): Easy, shaded walk with native trees – great for kids and stunning in autumn
• Seopjikoji Coastal Trail: Lighthouse views, waves crashing against cliffs, farmland scenery
• Bijaram Forest: An flat, easy forest walk that loops back and takes about an hour to complete – great for families year-round

Tips:

• Most trails are well-marked, but using Kakao maps can also be helpful in more rural areas
• Start early to avoid crowds at popular spots
• Many trails are stroller and kid friendly. You can check signage for difficulty (especially if you’re considering an Olle trail)

Did You Know?: Jeju trails let you explore Jeju’s biodiversity, endemic plants, and volcanic formations close up – so not only is it good exercise and a great way to explore the island, but it’s also educational and immersive – which is great for kids.

Jeju Nature and Outdoors – Practical Tips

If you’re considering a Jeju trip that will see you spend lots of time outdoors here are some things to consider to help make the most of your trip:

• Transportation: Renting a car is strongly recommended for accessing remote waterfalls, beaches, and lava tubes.
• Weather: Coastal winds can be strong if you’re coming in winter make sure you pack appropriately – with lots of layers and a good, thick jacket. Summer can be hot and humid – sunscreen and hats are essential. As is a water bottle if you’re planning on doing hikes and trails. Many trails wind through towns for restocking but Hallasan and more rural trails don’t – so be prepared.
• Seasonal Notes: Spring (April–May) brings cherry blossoms and mild temperatures; autumn (October–November) offers clear skies and stunning foliage (but trails on Hallasan can be incredibly busy so start out early).
