Where can you snorkel in Kosi bay?

Kosi Bay Mouth in the far north eastern corner of South Africa, offers a unique and world class snorkeling experience!

Our snorkeling tours are conducted by highly experienced marine guides within the mouth section of the Kosi bay estuary.

The systems freshwater needs are fed by groundwater and clear river systems from sand catchments. Together with the subtropical location, away from muddy river mouths, the water clarity when snorkeled on the correct tide is fantastically clear!

With every pushing tide, clear nutrient rich water push into the calmness of the bay. Here an ancient sandstone reef form our perfect snorkeling area.

Why snorkel with our experienced snorkeling guides?

At Kosi bay mouth the quality of your snorkeling experience hugely depends on snorkeling at the exact correct tide and place to avoid strong currents and to have the best visibility that the day will offer.

When snorkeling at Kosi bay mouth on the wrong tide the water will be green as the water will be flowing out of the system to the ocean and when snorkeling when the tide is pushing too hard, the current will be too strong to snorkel comfortably.

We will arrange to meet you at the perfectly ideal time to give you the best Snorkeling conditions that the given day will offer.
