There's a treehouse 110 feet up in the Peruvian Amazon where you wake up at eye level with spider monkeys and harpy eagles, and the conservationist who built it says the reason to go happens around 4 a.m. Watch him try to describe the jungle waking up. He makes it all the way to the macaws crossing the mist before he runs out of words and just makes a sound. He gets that every morning. It's called Alta Sanctuary, and you can book a night there on the Las Piedras River. The money from guests helps protect the forest around it, which is about the best excuse anyone's ever had to sleep 11 stories up in a tree.
