A giant head hidden in the forest, a maze named after a mythical creature and a wave chamber are just some of the things you'll find hidden away in and around Northern Europe's largest man-made forest.
And now that's been highlighted in the Guardian, after Kielder Art and Architecture was named as one of the best sculpture trails in the UK.
Seeing all of the artworks on and around the 26 mile shoreline of the reservoir is quite a task on foot - it's even ambitious on a bike. However, there are three suggested trails to download which start at Kielder Castle Visitor Centre, Leaplish Waterside Park and Hawkhope Car Park.
