Cors Caron is a huge raised peat bog in the Teifi valley near Tregaron, one of the finest in Britain and a National Nature Reserve. An accessible boardwalk loops out across the bog from the car park to a hide, good for red kites, otters and winter wildfowl. It’s open access and free, and the old railway line alongside makes an easy level walk or cycle.
