TreeHouse Point

Seven treehouses in old-growth forest on the Raging River, half an hour from Seattle.

Every treehouse here was built by Pete Nelson, the builder behind Treehouse Masters, and each has its own name and personality, from Temple of the Blue Moon to Bonbibi.

Grown-ups only (16 and up). There's a lodge, a bathhouse and, for the committed, a converted army truck to sleep in.
