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 short walk from the small parking area includes a circular boardwalk around the edge of the bog.
The walking trail is waymarked from start to finish.
Look out for the information panel at the start of the trail.
Cors Fochno is part of the Dyfi National Nature Reserve.

The landscape and wildlife varies at Cors Fochno depending on which time of year you visit – read on to find out what to look out for.
Many rare and specialised invertebrates survive here.
The waterlogged bog surface is a hostile place for most plants, and those that thrive here, like bog cotton, bog asphodel and bog myrtle, all have special adaptations.
Carnivorous plants also come into their own here including all three native species of sundews.
The most important bog specialist plants (and the main peat-formers), are the bog mosses or sphagnums, which form colourful carpets on the open bog and raise its surface into a shallow dome as their remains accumulate.
Fifteen species of bog moss occur here including three national rarities.
There are over 70 National Nature Reserves in Wales.
National Nature Reserves are areas of the countryside where special examples of Britain’s habitats and wildlife are protected.
