Are you planning your next vacation? Ditch the beach, and head to a tree. According to The Wall Street Journal, the hot new trend is the canopy vacation, where you climb sky-high trees and spend the night dangling hundreds of feet in the air in a hammock. What on earth would spark a trend like this? The fact that more and more people are eco-friendly. It’s not enough to clean their house with green products or drive hybrid cars. Now, they want a green vacation. Even though the economy is down, ecotourism - when people vacation in natural habitats - is on a tear - growing 5% a year. So, eco-resorts are popping up all over the world to meet the huge demand, and a lot of them charge hundreds of dollars a night for the privilege of sleeping in a tree.

There’s the Pacific Tree Climbing Institute in Oregon, where a guide leads you up a 300-foot tall tree and you spend the night dozing in a “Treeboat,” which is a heavy-duty hammock with a built-in 2 inch air mattress. Or, if you’re not the rugged type, Australia’s Cockatoo Hill Retreat is the canopy vacation for you. You can take in the incredible view of the country’s wildlife while relaxing in a one-bedroom tree house, complete with a balcony and mini-bar, perched 200 feet above a ridge.

You don’t have to be Indiana Jones to enjoy a canopy vacation. Experts say anyone from kids to seniors can do it. Scaling a 300-foot tree isn’t any harder than just walking uphill. According to The American College of Sports Medicine, tree climbing may sound intense, but consider this. Your body needs twice as much energy to go for a run than it does to climb a tree.
