Thornwick Bay is a rugged inlet located on the northern coast of the Flamborough Headland in East Yorkshire. The bay is characterized by dramatic chalk cliffs, sea caves, and a pebble beach accessible via a steep path. It forms part of the Flamborough Heritage Coast and serves as an important site for nesting seabirds, including kittiwakes and fulmars. The area is geologically significant for its exposed chalk strata and coastal erosion features. A seasonal cafe is located near the cliff top, providing views over the bay. The site is a popular destination for walkers traversing the cliff-top trails that connect to North Landing and Flamborough village.
