Bayhead Natural Heritage Site is a 20ha nature reserve of mangrove forest and coastal grassland within the industrial area of Durban Bay, South Africa.

[1] The reserve is a remnant of what was once the largest mangrove swamp in the province.

[4] As in the nearby Beachwood Mangrove Nature Reserve, various crabs can also be found.

[3] There is a boardwalk and public information centre on site.

In March 2015, a vegetable oil spill from a refinery in the area caused a number of mangrove trees to die.
