A relatively recent addition to Grand Cayman's eco-tour offerings is a night-time kayak tour into bioluminescent hot spots with guide, Tom Watling. It is a bit of a technological challenge and trick to capture the dim blue glow that we easily see with our eyes, by using a long exposure while the guys are frozen via a tiny flick of tightly directed flash. It's not as easy as it sounds. Tom did his best "glow angel" in the shallows to show off the intensity of the glowing microbes lighting up in response to his movements. Bioluminescence featured heavily in the forests of the epic 3D film, Avatar, which totally thrilled me.
