Cors Caron National Nature Reserve, near Tregaron

What's here


Cors Caron National Nature Reserve is a vast area of wetland filling the broad valley of the River Teifi near Tregaron.

The three raised peat bogs are surrounded by reedbeds, fen, wet grassland, woodland, waterways and ponds, and these varied habitats support a wealth of wildlife.

The fully accessible boardwalk goes over the south-east bog and to the large bog hide where you can enjoy a peaceful view of the landscape and wildlife.

The multi-user trail may be used by walkers, cyclists and horse riders, and follows on an old railway track along the edge of the reserve offering good views over Cors Caron.

National Nature Reserve

Cors Caron is a National Nature Reserve. 

This large reserve covers an area of over 800ha (or three square miles).

The three raised bogs are world famous – areas of deep peat that have built up over the last 12,000 years. They are some of the most intact examples of raised peat bogs in Britain, with millions of cubic metres of peat up to ten metres deep.

The River Teifi and its floodplain form the centre of the reserve and is internationally important in its own right as a European Special Area of Conservation (SAC); the extensive floodplain feels wild and remote.

The route of the old Aberystwyth to Carmarthen railway running along the margin of Cors Caron has developed a wide range of habitats since the railway’s closure in the 1960s.

This rich mix of habitats makes the reserve a fantastic place for wildlife. Red kite, hen harrier, curlew and skylark can fill the skies above the reserve, whilst the bog itself bustles with dragonflies, lizards and otters.

Welsh Raised Bogs Project

Cors Caron National Nature Reserve is one of seven places in the Welsh Raised Bogs Project.

This project is the first national restoration programme for raised bogs in Wales.

Cors Caron is one of the largest actively growing raised bogs in the lowlands of Britain and has peat up to 10 metres deep.

Raised bogs are one of Wales’ rarest and most important habitats and are home to rare plants and wildlife.

Raised bogs get their name because of their domed shape. They are areas of peat that have built up over 12,000 years and can be as deep as 12 metres.

To learn more about the restoration work, sign up for e-newsletters and read news releases go to the Raised Bogs project webpage.
