Visa-free indeed, but I really don't recommend visiting Jeju Island during the off-season from July to September because...

because it's too beautiful!!! Just returned from Jeju Island, and that lingering sense of relaxation hasn't faded yet. This small island, known as the "backyard of Jiangsu, Zhejiang, and Shanghai," truly holds too many unforgettable charms. After a 4-day, 3-night trip, every moment is worth savoring in detail. 🌿 Recommended 4-Day, 3-Night Relaxing Itinerary Day 1: First Encounter with the Island's Blue Head straight to Hamdeok Beach from the airport—the sea here is a clear turquoise-blue, and the sand is so fine it feels like walking on cotton. In the afternoon, visit Woljeongri and find a cozy café along the seaside coffee street. Order an iced Americano and watch the waves lazily lap against the shore rocks—time seems to slow down. Day 2: The Romance of Island Hopping Take a morning ferry to Udo Island and rent an electric bike for the most comfortable way to explore. The sea around Udo comes in multiple shades, from light blue to indigo. Along the way, you'll pass white sand beaches, black volcanic rocks, and spots where you can see haenyeo (female divers) at work. For lunch, try freshly caught conch sashimi—so fresh it’s mind-blowing. In the afternoon, return to Seongsan Ilchulbong (Sunrise Peak). You don’t need to wait for sunrise; the view from the top overlooking the volcanic crater and surrounding seascape is breathtaking. Day 3: Coastline and Sunset Visit the Windmill Coastal Road in the morning—white windmills spinning against the blue sky and distant sea create a scene straight out of a painting. For lunch, enjoy grilled Jeju black pork near Hyeopjae Beach. The pork is perfectly marbled, crispy on the edges, and juicy inside—wrap it in lettuce for ultimate satisfaction. Spend the afternoon leisurely wandering around Aewol-eup, where the sunset steals the show, painting the sea in golden-red hues and filling the air with a gentle warmth. Day 4: The Liveliness of the City Save the last day for the city. Explore Dongmun Market, where you must try spicy rice cakes with fish cakes, smothered in sweet-spicy sauce, and freshly made seafood pancakes—crispy on the outside and packed with seafood goodness. In the afternoon, pick up souvenirs at Lotte Duty Free before heading home with a heart full of memories. 🚌 Transportation Tips Jeju’s buses are convenient and cover most attractions. No need to carry exact change—many buses accept card payments. Taxis can be pricey, so for long distances, buses are the better option. 🏡 Accommodation Experience I stayed at two types of places, and the guesthouse won me over. The one I chose was a standalone house with two bedrooms, a living room, and a small yard planted with Jeju’s signature tangerine trees—unripe fruits hanging like a scene from a K-drama. The room was spotless and cozy, with bedding so soft I fell asleep instantly (and I’m picky about bedding). The kitchen, fridge, and utensils were fully equipped, making it easy to cook fresh seafood bought locally—far homier than eating out. The host was warm, fluent in English, and made my two-night stay delightful. 🍽️ Must-Try Foods - Grilled Black Pork: Jeju’s signature dish—firm yet tender, slightly charred at the edges, and heavenly with a sprinkle of sea salt. - Seafood Stew: Any seaside restaurant will serve a pot brimming with shrimp, squid, and shellfish in a broth so delicious you’ll want seconds. - Tangerine Desserts: The island’s tangerines are sweet and juicy. Try tangerine cakes, jellies, or juice for a refreshing treat. - Army Stew: Perfect for late nights—melty cheese, instant noodles, and spam in a spicy broth for the ultimate comfort food. Jeju’s beauty isn’t about ticking off attractions but slowing down to savor it—the morning sea breeze, afternoon sunlight, evening sunsets, and the lively hum of its streets. One visit, and you’ll understand why so many can’t wait to return.
