Cedar Creek Treehouse Observatory

Mount Rainer, Washington

This is a sight that everyone should try to see, but sadly, not a lot of people get the chance to. This tree house observatory has an unforgettable climb, that requires you taking an 82-foot spiral stairway. It’s one of the only cantilevered stairways on earth, built into a tree.

There’s just a centuries old tree, some nuts and bolts between you and a free fall, but when you hit the top, it’s worth it.
