Stair Hole

Stair Hole is a coastal feature located in Lulworth Cove, on the Jurassic Coast in Dorset, England. Although the question mentions Cornwall, Stair Hole is actually situated in Dorset, not Cornwall. It is a small, horseshoe-shaped cove that forms part of the larger Lulworth Cove. The cove is renowned for its unique geological formations, which make it a popular tourist destination.

Stair Hole is characterized by its steep cliffs and rugged rock formations, which have been shaped by erosion over millions of years. The cliff face is composed of layers of limestone and clay, which have been eroded at different rates, creating a distinctive stepped pattern that gives the cove its name.

One of the most notable features of Stair Hole is the natural arch known as the "Stair Hole Bridge," which spans the entrance to the cove. This arch was formed by the relentless pounding of waves against the limestone cliffs, gradually wearing away the softer layers of rock and leaving behind this impressive structure.

The cove is also home to several caves and rock pools, which are teeming with marine life. These pools provide a habitat for a diverse range of species, including crabs, starfish, and small fish, making it a popular spot for rock pool exploration and snorkeling.

Stair Hole offers visitors a unique opportunity to witness the power of erosion and see the geological processes that have shaped the coastline over millions of years. Its stunning natural beauty, combined with its rich biodiversity, make it a must-visit location for nature enthusiasts and geology enthusiasts alike.
