Jungle Surfing Canopy Tours. It's an exhilarating perspective on the rain forest and reef: suspended above the canopy on flying-fox zip lines, your speed controlled by guides, you whiz along (and if you like, flip upside-down) over lush rain forest and Mason's Creek, stopping at five tree platforms for killer bird's-eye views. Sessions last 1½ to 2 hours (A$90) and depart eight times a day starting at 7:45 am. Nightly guided Jungle Adventures Nightwalks (A$40) explore the critter-filled 45-acre grounds, departing PK's Jungle Village reception at 7:30 pm. Transfers from most local accommodations are free, or self-drive to the central departure point. Thrice-weekly day-tour packages from Port Douglas include lunch at Whet. Note that Jungle Surfing is unsuitable for anyone weighing more than 120 kilograms (260 pounds), and that children under 18 must bring a medical certificate and waiver before they'll be allowed to zip-line.
