A thousand tropical birds call the colours of the rainbow. Friendly monkeys scamper in ancient trees past low-hanging sloths through farms of butterflies. These are the sights and sounds that greet you as you walk across a jungle catwalk, 70 feet high in the Amazon treetops. You are making your way towards the Tarzan Room, built 110 feet up a mahogany tree. No, this is not the stuff of a Peter Pan adventure. It is a reality called Ariau Towers. This boutique hotel is the brain-child of eco-visionary, Dr. Francisco Ritta Bernardino and has welcomed luminaries from Bill Gates to Prince Charles. You can canoe through the flooded forest, past pink Dolphins, gasping in wonder at the primeval rainforest you experience on the way. Cultural tours and night walks let you experience the jungle for yourself. Or perhaps a spot of dangerous piranha fishing is more your thing. Incredibly, the hotel packs 4-star luxury into this rustic setting. There are two treetop amphitheatres, banqueting facilities and even a health club.
