Udo Peanut Ice Cream: Jeju's Sweetest Island Snack

Udo peanut ice cream (우도 땅콩 아이스크림) is a soft-serve ice cream specialty unique to Udo Island (우도), a small volcanic island accessible by ferry from Seongsan Port on Jeju's eastern coast. The ice cream is made with peanut-flavored soft serve and generously coated in finely ground roasted peanut powder, giving it a rich, nutty flavor unlike any other ice cream in Korea. What makes this treat special is the quality of Udo's peanuts. The island's volcanic soil and sea air create ideal growing conditions for peanuts with an exceptionally sweet, fragrant flavor. Udo peanuts (우도 땅콩) are so famous that they've become the island's defining product, and the ice cream has become the symbol of a day trip to Udo. The ice cream itself is a creamy, smooth soft-serve that melts slowly in the warm Jeju sun. The peanut powder coating adds texture and an earthy sweetness. Some vendors also offer the peanut soft serve packed into a small cone or cup, making it easy to enjoy while exploring the island by bicycle or electric scooter.

Udo Island has been known for its peanut cultivation for generations, taking advantage of the island's unique black volcanic soil. Farmers on the small island (just 6 km in circumference) developed a tradition of growing peanuts as one of their primary crops alongside other vegetables and grains. As Jeju became a major domestic and international tourist destination in the 1990s and 2000s, Udo Island developed as a popular day-trip excursion from Jeju. Local vendors began creating food products that showcased the island's famous peanuts. The soft-serve ice cream format — easy to eat while walking or cycling — perfectly suited the tourist context, and it became a must-try item almost overnight. Today, the sight of visitors holding a peanut ice cream cone while cycling around Udo's coastline is an iconic image of Korean tourism.

Udo peanut ice cream is an informal, on-the-go treat that is deeply tied to the experience of visiting the island.

Udo peanut ice cream is a modern food phenomenon born from Korea's domestic tourism boom, but it has become genuinely iconic. For Koreans, the phrase '우도 땅콩 아이스크림' instantly evokes images of Jeju Island, summer holidays, and carefree day trips. It features prominently on social media and travel blogs, and no visit to Jeju is considered complete without a ferry trip to Udo and an ice cream in hand. The ice cream also reflects how local agricultural products can be transformed into cultural attractions. Udo peanuts, once just a humble farm crop, are now a source of regional pride and economic sustenance for the island's small community. The success of the ice cream has spawned a whole industry of Udo peanut products available as gifts and souvenirs throughout Jeju.
