Kosi Bay

Kosi Bay is South Africa's most remote beach destination, lying just 10 km from the Mozambique border within the iSimangaliso Wetland Park. The Kosi Bay system comprises four interconnected lakes linked to the sea by a channel—a complex ecosystem of mangroves, raffia palms, and rare estuarine fish. The Tsonga people have built fish traps here for over 700 years, a practice still maintained today. The mouth beach offers pristine swimming in warm water with excellent snorkelling on the rocky outcrops. Hippos and crocodiles inhabit the upper lakes, while the lower reaches are safe for humans.
