Bridlington lies north-north-east of Beverley, south-east of Scarborough, north-east of Driffield and north of Kingston upon Hull, the principal city in the county. It is north of London. The height above sea level ranges from the beaches to on Bempton Lane on the outskirts. The Gypsey Race river flows through the town, the last being below ground from the Quay Road Car Park. The solid geology of the area is mainly from the Cretaceous period, consisting of Chalk overlain by Quaternary Boulder clay. The chalk is exposed as the land rises to the north of the town, where a cliff, probably formed in the last interglacial, extends inland at right angles to the present sea cliff, and forms the promontory of Flamborough Head.
