Bradda Hill, Mountain summit in Rushen, Isle of Man.

Bradda Hill is a mountain summit in Rushen on the Isle of Man, rising 233 meters above sea level with steep cliffs that descend toward Fleshwick Bay on the western coast. The landscape combines steep terrain with coastal views in a single prominent formation.

William Milner, a Liverpool locksmith, helped build a breakwater to shelter Port Erin from westerly gales in 1864 and organised charity for the poor. Grateful residents raised a tower in his honour by public subscription while he lived; it was finished in 1871 and its shape recalls one of the keys he made. A gorse fire burned the north and west slopes from 17 to 19 October 2003, and vegetation took over two years to return.

The hill carries both English and traditional Manx names, known locally as Cronk Vradda, reflecting the island's linguistic heritage. This dual naming shows how two cultures shaped the place over time.

Access is available via multiple hiking trails, including the Raad ny Foillan coastal path that connects from Port Erin village. Sturdy footwear is recommended since paths can be steep and slippery depending on weather conditions.

On the summit closest to the sea stands Milner's Tower, built in 1871 by public subscription to honour William Milner, a Liverpool locksmith who helped build Port Erin's breakwater in 1864 and organised charities for the poor. The tower's shape recalls one of the keys he made, and Milner held a reception for the whole neighbourhood when its first stone was laid.
