1. The Treehouse at Loch Goil, Argyll.
This beautiful, fairytale treehouse is perched in the branches of a pine tree right beside tranquil Loch Goil. It's particularly popular with couples, as you can get married in the historic, beautiful old lodge beside it, then stay in the treehouse for a real wedding night to remember (wink wink).
2. Fernie Castle Treehouse, Fife.
At over £400 a night, this luxurious, fantastical, hand-painted tree house in the grounds of Fernie Castle isn’t exactly affordable, but it's more magical than a herd of Harry Potters. The tree branches grow right up inside it, and it's got an awesome bath and a huge bed. Treat yo' self.
3. The Treehouse at Ackergill Tower, Caithness.
This ludicrously enchanting tree house is one of the largest in Europe, and sits nestled between the boughs of an old oak tree in the grounds of Ackergill Tower, a striking 15th-century castle just 17 miles from John O' Groats. It's built on two levels and has a circular bedroom with a seven-foot-wide round bed. Fancy.
4. Brochloch Treehouse, Dumfries and Galloway.
This cosy, romantic, awesome eco-retreat for two is situated in a bluebell-filled wood on a 190-acre working farm. It has a built-in double bed, a sofa, a gas stove, teeny-tiny little windows, and a bath with a huge skylight above it so you can see the stars (and the resident red squirrels). Amazing.
5. Kinlochlaich Treehouse, Argyll.
This adorable little house is built around a real, living tree trunk, which forms the central pillar for its lovely spiral staircase. It's hidden away in an 18th-century orchard overlooking a woodland burn. The balcony is shaded by a thick canopy of trees; you'll feel a million miles away from everywhere.
6. Craighead Tree Howf, Perthshire.
The Tree Howf is a hand-built wooden tree house with amazing views over the nearby Ochil Hills. It sits in the branches of an ancient ash tree, and has a wood burning stove, stained glass windows, and a "rustic" king-size bed made from reclaimed wood. There's also a viewing platform so that you can relax while looking down on a little nearby loch, or toss down treats to the resident pygmy goats.
Bonus treehouse: The Cedar Spire in Fife.
Sadly, this ambitious tree house isn't available as a holiday home (yet), but it's certainly worth a mention. It was designed by Gordon Brown, a talented Scottish designer who was asked to create a treehouse in the grounds of a grand estate in Fife for the owner's children. It's built in an ancient cedar, it has a tree deck with a dining area, a giant swing, and a zip-wire that "transports the more adventurous over 600 feet to a distant tree". Nice work, Gordon.
