Land's End (Cornish name: Penn an Wlas) is a headland on the Penwith peninsula, located near Penzance in Cornwall, England, United Kingdom. It is the most westerly tip of the English mainland (for Great Britain it is Corrachadh Mor). Visible from Land's End is the Longships Lighthouse. The Longships, a few miles out, is a serpentine and quartz island. Offshore, midway between Land's End and the Isles of Scilly, is the supposed location of the mythical lost land of Lyonesse, referred to in Arthurian literature.

The Logan Rock is an example of a logan or rocking stone. This geological feature is near the Cornish village of Treen in the Penwith district of Cornwall, United Kingdom. The rock is an eighty ton granite boulder perched on the edge of the cliffs overlooking the Atlantic ocean, on a headland one mile south of the village. The rock is finely balanced due to the actions of weathering, and prior to its restoration in 1824 it could be rocked by applying only a little pressure. The name Logan Rock is also applied to the surrounding tip of the headland, as well as the logan stone itself. Cripp's Cove lies to the east beneath the rock. The headland is also an Iron Age promontory fort called Treryn Dinas, defended by three ramparts. A number of islands are located around the edge of Logan Rock including Great Goular, Horrace, and Seghy.
