A beautiful bay on the north coast of Flamborough Head which is mainly rocky with a magnificent sea arch in the cliffs. Thornwick Bay Cafe sits on top of the cliff and overlooks the bay.


Popular with geology students and bird watchers. Access is via a mud track and steps, so quite restrictive to those with limited mobility. Popular with dog walkers and families.

What's tested here?

Water samples are not taken at this beach because it has not been designated as a bathing water and there is no voluntary sampling.
Why isn't this a designated bathing water?

High levels of bacteria in the water can indicate pollution from sewage treatment works or polluted rain water draining from the land.
Where does pollution comes from and how can you help?

Water quality can be reduced for up to 72 hours after heavy rain. Look out for temporary signs at the beach and on our website.
