It is over 5 km long, almost half of the width of the estuary at that point and a little as 45meters wide.
Spurn is designated as Heritage Coast, and is a nature reserve owned by Yorkshire Wildlife Trust since 1960, covering 113 hectares above high water and 181 hectares of foreshore. The mud flats are an important feeding ground for wading birds, and the area is a significant site in Europe for observing migrating birds. Many uncommon species are sighted there, such as the Black Browed Albatross (Diomedea melanophris). More commonly, birds such as the Wheater, Whinchat, Redstart and Flycatchers alight at Spurn on their way to breeding grounds elsewhere.
The peninsula is made up from sand and shingle eroded form the Holderness coastline washed down the coastline from Flamborough Point. Material is washed up by waves to form a long, narrow embankment in the sheltered waters inside the mouth of the Humber estuary. It is maintained by plants, especially Marram grass (Ammophila arenaria). Waves carry material along the peninsula to the tip, continually extending it. However, as the peninsual grows, it narrows.
Spurn has a 250-year cycle of destruction and reconstruction, as the sea cuts across the peninsula, and everything beyond the breach is swept away.
