Arthur's Seat is one of four hill forts, dating from around 2,000 years ago. Situated within Holyrood Park, as well as it's rich cultural heritage, the park offers walks, solace, wildlife, volcanic geology and unparalleled vistas of the city from its many vantage points. The park has several Site of Special Scientific Interest (SSSI) designations due to its exceptional range of grassland habitats and its internationally important volcanic geology. Ranger service on site.
