Stanner Hill

About Stanner Hill

Stanner Hill is a geological geriatric, boasting rocks roughly 700 million years old—officially the oldest in Wales. Its south-facing slopes enjoy a Mediterranean micro-climate, making it a posh retreat for rare flora like the Radnor lily, even if the local sheep aren't particularly impressed by the botany.

• •The rocks beneath your boots date back roughly 700 million years, officially making this the oldest dated rock sequence in southern Britain.
• •The hill serves as a sanctuary for the Radnor lily, an elusive yellow flower that thrives here thanks to a south-facing micro-climate that mimics the Mediterranean.
• •Geologists spent over 150 years squabbling over its origins, with theories ranging from Ancient Archean ridges to much younger Carboniferous intrusions before finally settling on its Precambrian roots.
• •It forms part of the Stanner-Hanter complex, a rugged igneous trio alongside Hanter Hill and Worsel Wood that stands out sharply against the softer surrounding landscape.
• •While its height is modest, the combination of steep slopes and ancient scree ensures you'll still be gasping for breath, providing all the exertion of a Highland peak with none of the altitude.
