More ways to explore the area's outdoor wonders
You step off the dock at Cairns Marlin Marina and the harbor contracts behind you: the engine note rises, spray cuts the light, and the mainland recedes. In an hour the color of the water shifts from blue-green to the electric turquoise of coral country. The vessel drops anchor beside bommies and plate corals; the guide briefs the small group and soon you slip into salt-cool water threaded with fish and the slow, deliberate motion of turtles.
