The man-made loch and forest has England's least light-polluted skies and its remotest village, Kielder, and rates as one of the UK's most tranquil spots.
However, when it comes to wildlife, Kielder Water and Forest Park is buzzing – the 155,000-acre wilderness is a stronghold of red squirrels, birds of prey, wild goats and rare plants. And this month, Kielder Partnership is staging the second Kielder Wildlife Month after last year's inaugural success.
Nature lovers are invited to hike in search of feral goats, which have roamed the border lands for centuries, and go on safari to seek elusive roe deer, badgers, owls, squirrels and bats. There will also be a special trip to Border Mires, England's biggest upland bog restoration project and one of the nation's greatest liquid assets.
The month ends with a spectacular day-long wildlife jamboree at Leaplish Waterside Park on May 31 with scores of activities for all the family.
Kielder Partnership director Elisabeth Rowark said: "Kielder Water and Forest Park is brimming with wildlife and incredible natural habitats. Wildlife Month is a terrific way for people of all ages to learn more about this special place and share the passion of those working to conserve our precious landscape, animals and plants."
And spokesman Richard Darn added: "Kielder is not just a really important producer of timber, it has also become of the nation's top wildlife habitats. In terms of ground covered, five per cent of all Sites Special of Scientific Interest in the UK are found in Kielder."
