On the left is a branch of the boardwalk leading to the excellent bird-hide.
An excellent board-walk allows access well into the bog with many good places to stop and observe the wildlife and vegetation of this site. Cors Caron is a raised bog system covering more than 800 acres (325 hectares). It is 6km in length and provides a habitat for a wide range of wildlife and plants. The bog itself was formed 12,000 years ago when the last of the Ice Age glaciers melted away. A large shallow lake was left, which very gradually filled with sediments and vegetation, forming peat and later, acid peat.
For centuries, local people would go and cut this peat from the bog to burn on the hearth. In 1955, Cors Caron was declared a National Nature Reserve in order to preserve this increasingly scarce land form. In 1993, Cors Caron was placed on a list of wetland sites of international importance under the terms of the Ramser Convention. The bog is now managed by the Countryside Council for Wales.
There are several good websites to see, this one being concise but informative:
