Lotte World Adventure Busan (롯데월드 어드벤처 부산)

Lotte World Adventure Busan is the Busan branch of Lotte World — Korea's major theme-park-and-entertainment chain — opened in 2022 as the country's largest new theme-park development of recent years. The park spans a large outdoor area in Osiria Tourism Complex on Busan's eastern coast, with multiple themed zones, a major roller-coaster attraction, family rides, themed seasonal events (parade-and-fireworks programming), restaurants and shops, and the park's signature character-driven entertainment identity. The Busan location pairs the theme park with the surrounding Osiria Coastal Walk and the broader Osiria area's beach-and-resort cluster. Best given a full day; pairs naturally with broader eastern-Busan itineraries that already include Osiria Coastal Walk and Haeundae Beach.
