Cors Fochno at Dyfi National Nature Reserve & Centre

Cors Fochno is part of the Dyfi National Nature Reserve, situated midway between Aberystwyth and Machynlleth. Known locally as Borth Bog, Cors Fochno is one of the largest and finest remaining examples of a raised peat bog in Britain - peat has been accumulating here gradually and continuously for over 6,000 years and now reaches a depth of over 6 metres.

The bog’s formation started around 5500 BC when part of the estuary floodplain was covered by forest, but as sea levels rose, the forest was replaced by reed swamp and then peat bog.

The most westerly part is now eroded by the sea, but at low tide the stumps of long dead trees can still be seen on the beach near Borth.

The bog’s surface today is dominated by a tapestry of green, gold and red sphagnum mosses and many rare and unusual species live here including insectivorous plants like sundews, the rosy marsh moth and small red damselfly.

The Wales Coast Path runs around the edge of Cors Fochno between Borth and Tre Tallesin.
