This long walk covers impressive expanses of ever-regenerating nature, with wildlife aplenty. Expect to see marsh harriers, herons, wading birds, marsh frogs, butterflies, dragonflies and much, much more — at any time of the year. You’ll also come across plenty of history going back thousands of years.
