Volcanic Craters and Sizzling Black Pork: Exploring Jeju Seongsan Ilchulbong & Udo Island (제주 성산일출봉 & 우도)
Following our stroll through the curved black-tile roofs and royal brass-bowl bibimbap halls of Jeonju Hanok Village, today’s travel guide takes flight across the southern sea to South Korea’s premier volcanic island paradise: Jeju Island (제주도).
Formed roughly 5,000 years ago by a dramatic hydrovolcanic eruption from a shallow seabed, Seongsan Ilchulbong (Sunrise Peak / 성산일출봉) rises like a massive, jagged green crown from the eastern coast of Jeju. Inscribed as a UNESCO World Natural Heritage Site, this towering tuff cone overlooks the turquoise waters separating the mainland from Udo Island (우도)—a serene cow-shaped islet famous for white coral beaches and roasted peanut treats. Down along the basalt coastline, travelers gather to savor Jeju’s ultimate culinary icons: thick cuts of charcoal-grilled Jeju Black Pork (흑돼지) and wild abalone feasts.

Highlights of Seongsan Ilchulbong & Eastern Jeju
- Seongsan Ilchulbong Crater Summit (성산일출봉 정상): A well-maintained, 25- to 30-minute wooden staircase trail winds up the steep western slope of the 182-meter volcanic cone, passing dramatic basalt rock formations along the way. At the summit, an expansive observation deck peers straight down into the bowl-shaped grassy crater—measuring 600 meters across—while offering sweeping 360-degree views of Mount Hallasan in the center of the island and the cobalt Pacific horizon.
- Jeju Haenyeo Women Divers Show (해녀물질공연): Directly along the rocky cove at the base of the southern cliff (Ummutgae), visitors can watch Jeju’s legendary Haenyeo (UNESCO Intangible Cultural Heritage)—elderly female free-divers who harvest conch, sea urchin, and abalone without oxygen tanks—perform traditional sea chants before diving into the surf and selling their fresh catch right on the rocks.
- Udo Island Day Excursion (우도): Just a 15-minute ferry ride from nearby Seongsan Pohang Port lies Udo ("Cow Island"). Visitors can circle the flat coastal road by rental electric scooter, bicycle, or hop-on-hop-off tour bus to visit Seobin Baeksa (a rare beach made of crushed red algae coral), Geommeolle Black Sand Beach, and Udobong Peak.
- Seopjikoji Coastal Cape (섭지코지): Located 10 minutes south of Sunrise Peak, this dramatic volcanic headland features rolling coastal grasslands, wild Jeju ponies, red volcanic scoria (songi) trails, and Tadao Ando’s minimalist architectural masterpieces, Glass House and Yumin Art Nouveau Collection.

What to Eat & Drink: Melted Anchovy Dip & Peanut Gelato
1. Charcoal-Grilled Jeju Black Pork (Jeju Heukdwaeji Geungogi / 흑돼지 근고기): Thick, bone-in cuts of indigenous Jeju black pork seared over glowing briquettes, dipped in bubbling Meljeot (fermented Jeju anchovy sauce simmered with garlic and chili) for an intense umami punch (Specialty BBQ houses near Seongsan & Jeju Black Pork Street).
2. Udo Peanut Ice Cream (Udo Ttangkong Ice Cream / 우도 땅콩 아이스크림): Creamy soft-serve gelato generously topped with crunchy, intensely nutty roasted peanuts grown in the mineral-rich, sea-breeze soils of Udo Island (Coastal cafes overlooking Udo’s Hagosudong & Geommeolle beaches).
3. Whole Abalone Stone-Pot Rice (Jeonbok Dolsotbap / 전복돌솥밥): Fragrant rice cooked inside a sizzling stone pot with rich green abalone liver paste, topped with tender sliced wild Jeju abalone and golden butter (Waterfront seafood restaurants along Seongsan Ilchul-ro).
4. Braised Whole Hairtail Fish (Tong-galchi Jorim / 통갈치조림): A dramatic, meter-long silver hairtail fish caught fresh off the Jeju coast, braised whole in a spicy-sweet radish and soy-chili reduction right at the table (Specialty seafood dining halls in Seongsan-eup).

Essential Visitor Tips
- Sunrise vs. Afternoon Lighting: As its name implies, Seongsan Ilchulbong is Korea's most famous spot to watch the sun rise out of the ocean. Check the exact sunrise time the night before and arrive at the ticket gate 40 minutes early for the climb. If you miss sunrise, visiting in the late afternoon provides warm golden light across the crater and smaller tour bus crowds.
- Free Coastal Cove Trail: If you prefer not to climb the steep stairs to the summit, the left-hand coastal trail leading down to the Haenyeo cove and dramatic sea cliffs is completely free to enter and offers remarkable upward views of the jagged tuff cliffs.
- Udo Ferry Passport Requirement: Foreign visitors boarding the ferry from Seongsan Port to Udo Island must present their physical passport (or Korean Alien Registration Card) when purchasing tickets and boarding, and must fill out two copies of the brief boarding declaration form at the terminal.
- Getting There from Jeju City: From Jeju International Airport, board express red bus No. 111 or 112 directly to the Seongsan Ilchulbong Entrance stop (approx. 1 hour 10 minutes), or take a rental car/taxi east along Ilju-dong-ro (approx. 55 minutes).
