Tunbridge Wells sandstone is Lower Cretaceous in age. It was lain down in large braided river channels. Today it's outcrops form upland regions across the Weald of Kent. In the Tunbridge Wells area there are several locally famous sites. Mount Edgecumbe Rocks TQ5739 : Edgecumbe Rocks, Wellington Rocks TQ5739 : Wellington Rocks, Tunbridge Wells Common, Toad Rock TQ5639 : Toad Rock, Rusthall, Happy Valley Rocks TQ5639 : Happy Valley Rocks, High Rocks TQ5638 : High Rocks, Eridge Rocks TQ5535 : Eridge Rocks, The Chiddingstone TQ5045 : The Chiding stone, Chiddingstone, Harrison Rocks
The rock makes for good rock climbing in the SE of England.
The rock is locally rich in Iron and mining it gave the Wealden area an Iron making industry in Mediaevil times. It also accounts for a number of Chalybeate springs across Kent and Sussex.

The Toad Rock (TQ5639 : Toad Rock from above on the sandstone ridge.) is a "Tor" like feature formed by a combination of physical & chemical weathering of Tunbridge Wells Sandstone. An Ice age relict feature. The Toad Rock is surrounded by other weirdly shaped outcrops, such as the loaf TQ5639 : The Loaf, the Elephant TQ5639 : Elephant Rock and the Lion TQ5639 : Lion Rock. The area has been designated as a Site of Special Scientific Interest. Part of Rusthall Common.
