Not any tree house, but the largest one in the world, and privately owned and closed to public. Can’t tell where the owner was (locked up), but the church he intended to build there was not an easy thing to accomplish and he deserves more credit or it. And for the record. we didn’t trespass, but followed the crowd saying the owner was inside but didn’t have the keys for the gate. Here are some pictures of probably the largest tree house in the world (Beehive Ln, Crossville, TN) :<

Bonus, some pictures from Burgess Falls nearby:
