Sejong National Arboretum (국립세종수목원)

Sejong National Arboretum, managed by the Korea Forest Service, is one of South Korea's largest urban arboretums and sits within the planned city of Sejong. The site spans a substantial area featuring themed garden zones — including temperate deciduous forests, conifer collections, and an indoor tropical greenhouse — alongside a dedicated plant research function. Visitors can walk extensive trail networks through seasonally changing landscapes, explore curated botanical collections, and visit exhibition halls focused on plant science. The arboretum serves both as a public green space for the Sejong metropolitan area and as a living repository of plant diversity.
