Williams Reef - Nova Scotia
Hayman Island Reef, out in the Coral Sea, isn't just another pretty face. This place feels like a well-kept secret, though it's right there. We usually drop in just after lunch, when the sun angles through the water and sets the coral alight. The sheer density of parrotfish here is something else. Schlegel's, Rainbow, Long-nosed, Dusky – they're everywhere, a constant crunching sound as they graze the reef, like popcorn in an empty cinema. Look for the Striped Catfish too, often schooling in tight, shimmering balls that ripple and morph. Our favourite spot is a shallow bommie on the western side. The Boring Clams nestled into the coral heads here are surprisingly vivid, some electric blue, others deep purple, often with a little Orbicular Batfish hovering nearby, almost inspecting them. We've had a few calm encounters with Flatback Sea Turtles gliding past, unhurried, on their way to wherever Flatback Sea Turtles go. The current here is generally mild, making it a relaxed dive suitable for newer divers looking for a proper reef experience without the usual anxieties of strong drift. Keep an eye out for the White-bellied Sea Eagle soaring above; it's a good marker for the shallower sections when you surface.
