Umhlanga Lagoon Nature Reserve is a 26-hectare area on the shore of the Indian ocean. The reserve encloses the Ohlanga River’s lagoon while the greater part lies inland of the busy M4 road. The reserve trails start at the car park at the northern end of Lagoon Drive, Umhlanga. The reserve has the remains of the prehistoric shell midden and walking trails with a walkway and pedestrian bridge that span the lagoon.
