Located at La Casa Del Arbol or “The Treehouse” in Baños, Ecuador, this small house was built for the stunning view on the Tungurahua Volcano it offers. But the real attraction is the swing attached to one of the tree's branches. It is far from your average swing, and it is surnamed the "Swing at the End of the World" for a good reason. Located off a giant cliff at over 2,600 meters above sea level and with absolutely no safety features, this swing promises a serious thrill to whoever is brave enough to ride it.

Clinging on with sticky toes, a green tree frog sits bravely on its unlikely friend – a large tree python. Curled around the branches of a small coconut tree, the snake appears relatively undisturbed by the bold passenger that has clambered onto its skin. Grown in captivity together, the pair display no signs of aggression or fear, comfortable with their encounters high up in the leafy branches. Photo enthusiast Fahmi Bhs watched in surprise as the frog slowly climbed along the scales of the metre long snake in a zoo in Jakarta, Indonesia. (Photo by Fahmi Bhs/Solent News/SIPA Press)
