Jeju Island is South Korea's premier holiday destination, often compared to Hawaii due to its volcanic origins and laid-back atmosphere. The geography is defined by Hallasan Mountain, a dormant volcano at the centre of the island, and the surrounding coastline of black basalt rocks and sandy coves. The climate is milder than the mainland, making it a viable destination even in late autumn or early spring.
Nature education is effortless here. Families can hike up Seongsan Ilchulbong (Sunrise Peak), a massive crater rising from the sea. The path is paved and involves many stairs, but the view from the rim is rewarding. Underground, the Manjanggul Lava Tube allows you to walk inside a massive volcanic tunnel; it is dark, cool, and damp, so sturdy shoes and a light jacket are essential even in summer. On the west coast, Hyeopjae Beach features shallow, turquoise waters ideal for young swimmers and sandcastle building.
Jeju is exceptionally catered to tourism, with a high density of quirky museums and theme parks. The Teddy Bear Museum, Hello Kitty Island, and the Chocolate Museum provide excellent rainy-day diversions. For a unique cultural experience, families can visit a tangerine farm to pick their own fruit (seasonally) or watch the Haenyeo—female free-divers, many in their 70s and 80s—harvest seafood without breathing equipment, a UNESCO-recognized tradition.
Public transport exists but can be slow; renting a car is highly recommended for families to maximize flexibility. The drive along the coastal roads offers plenty of stops for photos and cafes. Food highlights include grilled black pork (a local speciality) and hallabong (citrus) juice. Visitors should note that flights from Seoul to Jeju are frequent, but booking well in advance is necessary during holidays.

Urban tourism, museums, historical sites, architecture
