Portsea Pier - Victoria
Simio Bipolar isn’t your typical cenote dive, and that’s precisely why we love it. Instead of cavern walls, you’ll find yourself drifting over a vast, flat sandy bottom dotted with what feel like secret coral islands. We’re talking big, healthy mustard hill corals and branched finger corals rising like small hills, absolutely swarming with French grunts and sergeant majors. It’s a site that rewards a slow, observant approach. Keep an eye out for the spotted goatfish rummaging in the sand, and we’ve had some incredible luck spotting green and hawksbill turtles just cruising by. Visibility here usually sits around 14 meters, which feels expansive over the bright sand. While the current description mentions eagle rays, we’ve personally never seen one here. Instead, it’s the sheer density of the smaller reef fish on those coral bommies that really makes Simio Bipolar shine. It's an easy-going dive, perfect for newer divers looking for a relaxed experience, or experienced divers who appreciate the quiet beauty of a healthy, shallow reef in an unexpected setting.
