Established in 1911, the Mount Airy Forest covers an impressive 1459 acres and includes natural areas, planned landscapes, buildings, structures, and landscape features. The numerous hiking trails, bridle paths, walls, gardens, pedestrian bridges, and various other improvements within Mount Airy Forest reflect the ambitious park planning and development that took place in Cincinnati in the early-to-mid-20th century. Conceived as the nation’s first urban reforestation project, the park has developed over the years—especially during the Depression and post-World War II period- into a park with a variety of areas, spaces and structures designed to accommodate recreational, social, and educational activities. Today it continues to offer a large expanse of protected land within the city limits where the public can enjoy the richness and diversity of nature.
