The two beaches are part of a long strip of sand and are connected to each other below Orcombe Point at low tide.
Sited high upon the hill, Orcombe Point is marked by the "Geoneedle", which was unveiled by Prince Charles, in 2002, at the inauguration.
The coastal exposures along the coastline provide a continuous sequence of Triassic, Jurassic and Cretaceous rock formations spanning approximately 185 million years of the Earth's history.
The ascent to Orcombe Point shows the successive layers of different sedimentary rocks, which were deposited under varying geological conditions.
These formations belong to the Aylesbeare Mudstone Group and date from the Triassic period 250 million years ago.
