St Augustine's Church sits on the highest point of the Head and has been used as a landmark to aid navigation for seafarers for centuries. When the medieval church was replaced in the 1860s, Bristol Channel pilots demanded the new church had a tall tower. William Butterfield's new church was built with a 90-foot tower.
In 2015 a viewing platform was built in Penarth Head Park, which lies on the edge of the Head at the end of Penarth Head Lane. The park, with views to Penarth Pier and across to Flat Holm, was to have interpretation boards, as well as a mosaic in the shape of the Wales Coast Path logo. At 200 feet above sea level, the park is the highest point on the entire route of the Wales Coast Path.
