Cromer Shoal Chalk Beds

Site overview: This site features the longest chalk reef known in Europe - possibly the longest in the world, stretching on for 20 miles! In fact, it has even been suggested that this site should be re-named The Great Barrier Reef of Norfolk. It is located just 200 meters from the Norfolk coast and includes arch formations in the chalk walls which can be up to 20 metres high.
