Mumbles Hill is a hill near the south eastern tip of the Gower Peninsula, Wales. Parts of the hill form a designated Local Nature Reserve, declared in 1991. Defensive gunnery positions were built on the hill in World War II. Remnants of the 623rd Anti-Aircraft Battery gun emplacements and control bunker are still visible on the hill. Coastal Defence Battery 299 had a site on a hill with 6 inch gun and underground magazines, though none of this remains on the hill. However there are information boards marking the spot.
