Off to one side of the lake is a copse of trees that arch so high up in the sky, it's nearly impossible to see where their leafy tops end. But at the bottom of one is a rope ladder and a winding wooden staircase that wraps around the thickest trunk of the trees and leads up into the sky.

If you dare to ascend the ladder or the staircase, you'll be rewarded by entering the Giant Treehouse, which looks something like a cross between a log cabin and a miniature Hogwarts castle. The treehouse has a large veranda with rocking chairs on it and is completely surrounding and supported by the trunks of at least three trees, so it feels fairly stable even though it's suspended waaaaaaaaaay up in the air. The inside of the treehouse contains a few empty rooms, a tower, and a loft, but there are pillows and blankets, spare bits of parchment, ink and quills, and a bucket on a rope and pulley that goes all the way to the bottom of the tree. The treehouse looks (and smells!) brand-new, with nice new windows and fairy lights that illuminate the treehouse at dusktime.

No one said Williamson didn't still have the heart of a kid sometimes. He built this just for you.

And don't wory about falling out of the treehouse; there are a LOT of spells protecting and supporting the giant treehouse. If you were to fall from the treehouse or its platform, your fall would be slowed by magic. Plus, the ground below the treehouse has been charmed to feel like the equivalent of a squishy gym mat. Be careful though; too much horseplay will result in the grumpy groundskeeper shutting things down or turning this into his personal fort where kids can't find him.
