Balch Cave (grid reference ST65734753) is a cave in Fairy Cave Quarry, near Stoke St Michael in the limestone of the Mendip Hills, in Somerset, England. The cave is part of the complex of passages feeding to St. Dunstan's Well Catchment Site of Special Scientific Interest and an abandoned Bristol Water abstraction point. It is named in honour of Herbert E. Balch who was famous for his exploration of the Caves of the Mendip Hills. The cave was broken into by quarry blasting in November 1961. Much of the cave has since been quarried away and by the end of the 1960s, major sections were destroyed.
