The Atlanta Beltline Arboretum stands as the world’s longest linear arboretum, marking a global milestone in urban greening, ecological restoration and sustainable redevelopment. The 12.44-mile botanical collection is redefining how cities integrate nature, infrastructure and public space. As new sections of the Atlanta Beltline open, the arboretum continues to grow, reaching 16.7 miles of trail by summer 2026 and progressing toward completion of the full 22-mile loop by 2030.
