At the far northern end of the Route22 corridor, just below the Mozambique border, Kosi Bay is a chain of four linked lakes that drains to the sea through a clear, sheltered estuary. Local fishers still build and use traditional reed and wood fish traps here, a practice handed down for generations, and the estuary mouth is one of the best snorkelling spots on the KwaZulu-Natal coast.
The traditional fish traps
The fish traps are fences of wooden stakes and reeds built across the channels, with funnels that guide fish into enclosures at the right tide. Each trap belongs to a family, and they are still maintained and fished today. The best views are from the lake shores and on guided boat trips. Look, photograph and enjoy, but never enter or touch a trap.
Snorkelling at the Kosi mouth
Where the estuary meets the sea, the water is often clear and full of reef fish, especially around the incoming tide. Go with a local guide who knows the tides and currents, take your own mask and snorkel, and never swim in the channel when the tide is running out.
Access, 4x4 and permits
The lakes and lodges are reached by road, but the Kosi mouth and the beaches at Bhanga Nek are on sandy tracks that need a 4x4. Access to the mouth is controlled by iSimangaliso with a limited number of permits per day, so arrange it in advance through your accommodation or a guide.
Lakes, birding and turtles
Guided canoe and boat trips explore the lakes and raffia palm forest, home to the rare palm-nut vulture. In summer, the beaches around Bhanga Nek are among the most important turtle nesting sites in South Africa, with community-run turtle tours.
Frequently asked questions
Do I need a 4x4 for Kosi Bay?
You can reach the Kosi lakes and most accommodation in a normal car, but the Kosi mouth and Bhanga Nek beaches are on deep sand tracks that need a 4x4, or a guided trip that includes transport.
Do I need a permit for the Kosi mouth?
Yes. Access is managed by iSimangaliso and the number of vehicles per day is limited, so book a permit or a guided trip in advance.
When is the best time to snorkel at Kosi Bay?
Calm days around the incoming tide usually give the clearest water and safest conditions. Ask a local guide for the day's tide times.
Can I visit the fish traps?
You can see and photograph them from the shore or on a guided boat trip. They are private and actively fished, so never enter or disturb them.
