Jeju operates on its own logic. This volcanic island, 85km off the southern tip of the Korean peninsula, was an independent kingdom for centuries and still carries itself like one. The dialect is different, the food is different, the landscape is otherworldly — and the haenyeo, the elderly diving women who free-dive to 20 meters to harvest the sea floor, are a living UNESCO heritage site that you can watch at work along the eastern coast.
We came to Jeju for three nights and stayed for six. The island just kept revealing itself — a new trail, a hidden beach cove, an octopus-pot restaurant on the harbor where the haenyeo eat after their morning dives. Jenice was particularly taken with the haenyeo culture; we ended up attending a demonstration three times.
Getting Around Jeju
A rental car is not optional — it’s essential. Jeju has buses, but the island is 73km east-west, and the good stuff is scattered in all directions from Jeju City. Compact car rentals are ₩40,000-60,000/day from airport desks (Lotte, SK, AJ Rent-a-Car). You’ll need an International Driving Permit — get one before you leave home. Gas is more expensive on Jeju than the mainland. Download Naver Maps for offline use — it handles Jeju’s smaller roads better than Google.
Things to Do on Jeju
Hallasan National Park is dominated by South Korea’s highest mountain (1,950m) — an ancient shield volcano that last erupted in 1007 CE. There are five trails; the Yeongsil Trail (3.7km each way, ~4 hours round trip) is the most scenic, rising through ancient forest and cloud zones to a high mountain shelter. The Witseoreum Trail continues to the summit crater lake (Baengnokdam) — allow 7-8 hours round trip. No fee for the park; trailheads close at specific times so check the Jeju National Park website. Weather changes fast above 1,500m — bring layers regardless of what you’re wearing at the base.
Seongsan Ilchulbong (Sunrise Peak) is Jeju’s most iconic sight — a 182m volcanic crater that rises directly from the sea in the island’s northeast corner. The UNESCO World Heritage site takes 20-30 minutes to climb; the crater views are extraordinary at any time of day, but the 5:30 AM sunrise crowds arrive in force. ₩5,000/adult. The haenyeo demonstration area at the base has free performances.
Manjanggul Lava Tube is 13.4km long — one of the world’s greatest lava tubes. The accessible 1km section features dramatically lit passageways, bizarre lava formations, and the world’s largest lava column (7.6m tall). The temperature inside is a constant 11°C year-round. ₩4,000/adult. Allow 1-1.5 hours.
Haenyeo Experience — Jeju’s traditional female free-divers (haenyeo) are one of Korea’s most significant living cultural traditions. The oldest active haenyeo are in their 80s. You can watch them dive at Seongsan Ilchulbong base area, at the Haenyeo Cultural Center, or along the northeastern coast in the early morning. They harvest sea urchin, abalone, conch, and octopus — often eaten raw right on the dock.
Jeju Olle Trail is a 437km network of 26 walking routes circumnavigating the island’s coastline and inland areas. Each “Course” is 15-20km and takes a full day. Course 1 (Seongsan to Oreum) is the classic start, with ocean views and gentle terrain. The trail is marked with blue-and-orange ribbons; Naver Maps has the routes. The Jeju Olle Trail website has English route descriptions.
Jeju Folk Village Museum reconstructs traditional Jeju life across 100+ authentic buildings relocated from around the island. More engaging than it sounds — the village demonstrates how dramatically Jeju’s culture differed from the mainland. ₩11,000/adult.
Jeju Spirited Garden (Bunjae Artpia) — An extraordinary private bonsai garden created over 30 years, with ancient trees shaped by a single artist. One of Korea’s more unusual and meditative cultural sites. ₩12,000/adult.
Where to Eat on Jeju
Heukdwaeji (Black Pig) BBQ — Jeju’s iconic black-bristled pigs produce uniquely flavored, marbled pork. Every restaurant on the island serves it; the concentration of black pig restaurants near Jeju City’s old port area (Hyeopjae and Dokpuri neighborhoods) is the epicenter. Samgyeopsal (pork belly) and moksal (neck) are the cuts. ₩15,000-22,000/portion. Order without sauce first — the pork is good enough to appreciate pure.
Haenyeo Raw Seafood — Find the haenyeo lunch restaurants near Udo Island, Sehwa Port, or Bukchon fishing village. The morning divers eat together and often sell their catch directly at small restaurants. Sea urchin (urchin rice), abalone porridge, and raw octopus sliced tableside. The most authentic seafood experience in Korea. ₩15,000-30,000/person.
Dongmun Traditional Market — Jeju City’s best traditional market. Hallabong tangerines (the sweet mandarin variety unique to Jeju), black pork jerky, dried seafood, and haenyeo-caught items. Best in the morning. ₩3,000-15,000/item.
Okdomgui (Red Tilefish) — Jeju’s signature fish, salted and air-dried before grilling. Served with multiple side dishes and rice. Seogwipo restaurants near the southern port are known for this. ₩15,000-20,000/set.
Goseongmotguksu (Seogwipo) — Pork-based noodle soup unique to Jeju’s southern city, Seogwipo. Dark, rich broth, hand-cut noodles, local kimchi. ₩8,000/bowl.
Where to Stay on Jeju
Lotte Hotel Jeju (Luxury) — ₩280,000+/night. In Jungmun resort complex. The pool facility is the best on the island; beach access and multiple restaurants.
The Shilla Jeju (Luxury) — ₩350,000+/night. More traditional Korean luxury aesthetic. On a hilltop with ocean views and serene gardens.
Ramada by Wyndham Jeju (Mid-range) — ₩120,000-150,000/night. Central Jeju City location, comfortable rooms, walking distance to Dongmun Market and the old port.
Maison Glad Jeju (Mid-range Boutique) — ₩150,000-200,000/night. Near Hamdeok Beach on the northeast coast — one of Jeju’s most beautiful beaches for calm swimming.
Jeju Hiking Club Guesthouse (Budget) — ₩35,000-45,000. Basic but friendly. Gear storage, trail maps, and fellow hikers who can advise on current trail conditions.
Scott’s Pro Tips for Jeju
1. Logistics & Getting There: Fly from Gimpo Airport (Seoul domestic) to Jeju International Airport (CJU) — 1 hour, ₩40,000-90,000 depending on booking timing. The Seoul-Jeju route is the world’s busiest domestic air route; book at least 2-3 weeks ahead for April and October. You can also fly from Gimhae (Busan) or Incheon (international). Ferries from Mokpo take 13+ hours — not worth it unless you’re bringing a vehicle.
2. Best Time to Visit: Late March through early April for the famous yellow canola (rapeseed) fields. Cherry blossoms follow in early-to-mid April. October is spectacular for autumn colors on Hallasan’s slopes and comfortable hiking weather. July-August is peak domestic tourism — beaches are packed, accommodations are 30-50% more expensive.
3. Getting Around: Rent a car at the airport — full stop. Jeju’s public buses are workable but impractical for the Olle Trail, Manjanggul, and Hallasan. An International Driving Permit is required. Naver Maps handles Jeju better than Google, especially for smaller coastal roads and oreum trails. Fuel up at CJ One or SK Energy stations.
4. Money & ATMs: Jeju City has Global ATMs at all major convenience stores and at the airport. In remote areas (Olle Trail sections, oreum trails) cash is often the only option. Keep ₩80,000-100,000 for smaller villages, haenyeo restaurants, and rural entry fees.
5. Safety & Health: Hallasan weather changes fast above 1,500m — always bring a rain layer even on clear mornings. The sea around Jeju has dangerous currents at certain beaches; swim only at designated beaches with lifeguards. Jeju National University Hospital (+82-64-717-1114) is the main hospital in Jeju City. Emergency: 112 (police), 119 (ambulance).
6. Packing Essentials: Good hiking shoes or trail runners for Hallasan and Olle Trail. Layers even in summer (Hallasan summit is cold). Rain jacket — Jeju gets significant rainfall year-round. Sunscreen for coastal and mountaintop UV exposure. Download Jeju Olle Trail app and Naver Maps offline.
7. Local Culture & Etiquette: Jeju has its own dialect (Jeju-eo) so distinct it’s considered a UNESCO endangered language — mainland Koreans can’t understand most of it. Locals find it charming if you try a single Jeju phrase: “Oraeng” (hello/how are you in Jeju dialect). Haenyeo are treated with deep respect in Jeju culture — watch quietly and don’t disturb them while they work. The village guardian statues (dol hareubang — stone grandfathers) are a Jeju cultural symbol; avoid climbing on them.
