The Humber Estuary opens out at Spurn Head. Spurn is a spit of land that juts out into the North Sea.
It used to have a thriving town. It used to be an important military base. Now it is a great nature reserve.
Tens of thousands of birds come to feed on its rich estuarine mud with its invertebrate life.
The water’s edge is alive with many thousands of rare wading birds.
It is fabulous to see.
