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.

Hilary Norton from Visit Kielder says that it's brilliant for the area to be named on the list, but is keen to point out that Kielder Art and Architecture is not a sculpture trail.
She said: "You can't just go from one thing to the other, but we get very good feedback on individual sites or those who try and do a couple by walking or cycling.
"I think like any art, people have different responses to it. The majority of pieces reflect the landscape and I think people like that.
"People really love the playfulness of things like the Forest Head."
The Forest Head of which she speaks, also known as Silvas Capitalis is one of the best-known works around the lake, and a highlight for many who visit. The timber head has stood on the Lakeside Way since 2009 and from inside the sculpture, visitors can listen to the forest through its ears as well as watching it through its eyes.
Miguel Belo, who moved to Newcastle from Coventry, visited Silvas Capitalis with his sister Sara in February 2019. He said: "The sculpture is quite unique and it looks like it belongs there.
"It's very natural, as though it belongs in the forest. I found it amazing because you still feel you're in nature but at the same time there's this very amazing head... In the middle of the forest."
Miguel parked at Bakethin Reservoir, from which it's just under an hour on foot to the Forest Head.
He continued: "The walk was interesting - it was a very rainy day. It was raining so much we got absolutely soaked, but we persevered and when we got there in the end it was definitely worth it."
Other popular artworks along the trail include the Salmon Cubes, which reflect on the life cycle of the River Tyne's Salmon; Minotaur, a maze by Kielder Castle made of rocks and green glass; and the Wave Chamber, a camera obscura-style structure which projects an image of the lake's surface onto the floor inside.
The original article in the Guardian by Annabelle Thorpe said: "Over the past 27 years, the stunning landscapes around Kielder Water – and the dense forest beside it – have become home to an extraordinary collection of visual art and architecture, featuring everything from wave chambers to futuristic shelters.
"Highlights include Silvas Capitalis, a giant, open-mouthed head, and the Janus Chairs, three king-size rotating seats, which overlook the lake from the north shore. There are three art and architecture trail guides that can be downloaded from the website before visiting."
There is no cost to enter Kielder Art and Architecture - though there is a fee for parking.
