World's Best Treehouse Hotels

Why It’s Unique: Tucked 50 feet up in the air in a centuries-old cedar and bordering Gifford Pinchot National Forest, the Cedar Creek Treehouse is outfitted with a sleeping loft, kitchen, and glass-enclosed observation room with indoor hammock.

Access: Winding stairwell.

What to Do: Take in even greater views from the recently added observatory—100 feet up a nearby fir tree—which looks out on majestic Mount Rainier. Or, drive 10 minutes for a day hike in stunning Mount Rainier National Park.
