The park was funded entirely by SK Energy as a gift to the city of Ulsan, marking a significant private-sector urban environmental project.
The botanical garden contains an indoor climate-controlled dome housing rare tropical plant species year-round.
The water purification system processes approximately 50,000 tons of water daily to maintain the park's ponds and streams.
The rose garden is the site of the annual Ulsan Rose Festival, which attracts large crowds during peak bloom in late spring.
The park occupies a space that was previously used for military and industrial purposes, demonstrating a massive land-reclamation effort.
Ulsan Grand Park is the largest eco-friendly park in South Korea, spanning 3.64 square kilometers within the urban center of Nam-gu. It features a sophisticated water purification system that treats polluted water from the Gaeun-cheon stream before it flows into the Taehwa River. The park includes a dedicated Rose Garden housing over 50,000 rose bushes representing hundreds of varieties. Visitors can explore a butterfly arboretum, a tropical botanical garden, and a bird park that allows for close-up animal observation. Extensive walking and cycling trails navigate through dense forested areas and open plazas. Public facilities include children's playgrounds, a small zoo, and multiple multi-purpose sports fields. The park serves as a green lung for Ulsan, designed to balance heavy industrial surroundings with extensive natural vegetation.
