Braunton Burrows are the core of the country's first Man and the Biosphere Reserve. It is a world-class designation that makes the status of the area equal to that of other world-wide Biosphere Reserves such as the Danube Delta, the Hawaiian Islands and the Great Gobi. North Devon is a UNESCO Biosphere Reserve because of its blend of special landscapes and wildlife areas, rich cultural heritage and communities that care about it and want to sustain it into the future.

Exmoor Zoo is different, neither a wildlife park or a city zoo, but a more friendly and contact orientated zoo which has grown into the North Devon countryside. You get to meet the animals, join in the handling sessions, touch a snake, hold a spider, feed a wallaby and learn about the animals during talks and feed times.
