Jeju’s changing weather adds diversity to repeat visits, with each season offering something new.

Climb Hallasan: Korea’s Highest Peak

Towering at 1,950 metres, Hallasan is a dormant volcano located at the centre of Jeju Island. It’s the highest mountain in South Korea and a must-do for outdoor lovers. There are several trails to the summit, ranging from moderate to challenging. The Seongpanak and Gwaneumsa trails are the most popular, offering panoramic views and diverse flora. Even if you don't reach the summit, shorter trails still provide incredible scenery. In spring and autumn, Hallasan is particularly beautiful with wildflowers and golden leaves. The crater lake at the top, Baengnokdam, adds to the stunning visual reward. The trails are well-marked, and permits aren't required, but arriving early is recommended. Dress in layers and bring water, as weather changes quickly at higher altitudes. Wildlife such as roe deer and rare birds can often be spotted along the trail. In winter, snow-dusted landscapes turn the hike into a magical experience. There's also a visitor centre at the base with maps and local insights. Hallasan is a UNESCO Biosphere Reserve, so it's important to follow eco-friendly practices. This is a great way to connect with Jeju’s volcanic heritage while staying active. Hikers should allow a full day for the round trip to the summit. To include this adventure in your itinerary, the Grand Journey of Japan & South Korea tour offers guided access and transport options.

What is so special about Jeju Island?
Jeju Island is a volcanic paradise known for its stunning natural landscapes, including Hallasan Mountain and unique lava tubes. Its pristine beaches and crystal-clear waters offer the perfect escape for relaxation and water activities. The island is also home to the iconic Haenyeo women divers, showcasing a fascinating and resilient local culture. With its mild climate and seasonal beauty, Jeju is an ideal year-round destination. This peaceful island blends natural wonder with rich heritage, making it one of South Korea’s most enchanting places to visit.

Learn from the Haenyeo Women Divers

The Haenyeo are Jeju’s iconic female free-divers who harvest seafood without oxygen tanks. This centuries-old tradition is recognised by UNESCO for its cultural value. These women, often in their 60s and 70s, dive up to 10 metres to gather shellfish, seaweed, and abalone. Watching them work is a fascinating glimpse into Jeju's matriarchal heritage. Visitors can observe the divers in action or visit the Haenyeo Museum to learn about their lives and skills. The museum includes personal stories, equipment displays, and documentary footage. The Haenyeo represent strength, resilience, and a deep respect for nature. Their sustainable fishing practices are also a lesson in environmental harmony. Jeju Island, South Korea, is the only place in the country where this tradition still thrives today.

Seasonal demonstrations take place at specific coastal areas for tourists. The Haenyeo’s chants and rituals are rooted in spiritual beliefs passed down for generations. You’ll often see them selling their fresh catches at nearby markets after a dive. This culture offers a rare look at female-led industry in a male-dominated world. Children can take part in educational activities to understand their bravery and skill. It’s a living tradition that speaks volumes about the island’s cultural identity. For deeper cultural immersion, the South Korea and Japan Odyssey tour includes key cultural experiences in both countries, including Jeju.

Relax on Jeju’s Scenic Beaches

If beach time is on your list, Jeju doesn’t disappoint. The island is home to some of the most beautiful beaches in South Korea. Hamdeok Beach is ideal for families with its calm, shallow waters and clean white sand. Jungmun Saekdal Beach is popular among surfers and offers dramatic cliffs and turquoise waves. Hyeopjae Beach, with its clear water and black lava rocks, is perfect for photography and snorkelling. Many beaches have boardwalks, seafood restaurants, and cafés for a relaxed day by the sea. Summer is the best time for beachgoers, though spring and autumn also offer pleasant seaside weather. Water sports like kayaking, paddleboarding, and jet skiing are widely available. Sunsets on Jeju’s west coast are particularly breathtaking. Lifeguards are present at major beaches during peak seasons. The beaches are also clean and well-maintained, with facilities for showers and rentals. If you're lucky, you might spot dolphins off the coast or local fishermen at work. Families, couples, and solo travellers alike find Jeju’s beaches safe and welcoming. Quiet coves and rocky shores provide secluded spots for peaceful reflection. Beach festivals and night markets add excitement during the summer months. To pair Jeju’s coastline with broader travel, try the Best of Asia tour, which offers both island beauty and city lights.

An interesting fact about the Manjanggul Lava Tube is that it’s home to a giant lava column, which stands about 7.6 metres tall and is one of the largest of its kind in the world.
