7 Miles Reef - Sodwana Bay

Caster Rock is one of those places we keep coming back to in False Bay, especially when the southwesterlies are kicking up a fuss. It’s pretty shallow, topping out at 19 metres, which makes it an easy dive for almost anyone. We love the feeling of the mild surge pushing us gently over the granite outcrops, exploring the small gullies and overhangs. You'll find some impressive three-tooth cavoline here, usually cruising around the larger boulders, and we’ve spotted blue stingrays tucked into the sand patches. The sea lettuce is incredibly vibrant, a real burst of green against the darker rock. Visibility averages around seven metres, so it’s not always gin-clear, but we think it’s consistently good enough to enjoy the details. Our favourite time to dive Caster Rock is on a calm morning, just as the sun starts to properly illuminate the reef, making the reds and oranges really pop. It’s a peaceful dive, and a great way to ease into a day of exploring False Bay.
