The true summit is marked by a triangulation pillar approximately from the main Test Way. Before the use of satellites was commonplace, Walbury Hill was occasionally used by the BBC as a temporary relay station during the Newbury Races. There is no metalled road across the hill, but the byway is open to all traffic and maintained with a hard gravel surface, because of its previous use by outside broadcast vehicles. The ridged summit is also popular with paragliding enthusiasts.
