Jaw-dropping geology from Strumble Head to Cardigan

Folded cliffs of Gernos

Shaped by nature over millions of years, the landscape between Strumble Head and Cardigan is rocky, rugged and remote. As well as jaw-dropping geology, there’s heaps of history to uncover too, from Iron Age settlements to wartime invasions.

Garn Fawr

This rocky outcrop, formed by volcanic activity, provides magnificent views of the North Pembrokeshire coast. It was both an Iron Age fort, and a lookout post in the Second World War. It's close to a Youth Hostel, and to the lighthouse and seabird lookout at Strumble Head.

Ciliau Moor

Ciliau Moor is a fine stretch of wet coastal heathland, once grazed by commoners' cattle but now much overgrown. It's rich in bird life and actually overlooks the scene of the last French invasion of the UK mainland in 1797. This was defeated by local forces led by Colonel Campbell from Stackpole and Sir John Colby.

Pen Anglas

The coastline of Strumble Head was shaped by volcanic activity. Pen Anglas has an example of the sort of six-sided basalt column also seen at the Giant’s Causeway in Northern Ireland and on Staffa in the Hebrides. Pen Anglas contains an impressive expanse of coastal heathland, rich in colour in late summer.

Dinas Island

The channel that almost cuts off this headland from the mainland was formed by glacial meltwaters. Dinas has been farmed since the 16th century – Ronald Lockley, the famous naturalist, farmed here in the 1940s before moving on to Skomer Island.

Pen yr Afr and Gernos

These are the highest sea cliffs in Pembrokeshire, and this is one of the most challenging sections of the 184-mile Wales Coast Path. The rocks, with their spectacular folds and faults, consist of sandstone and mudstone laid down 450 million years ago.
