The Sundays River Estuary is a significant estuarine ecosystem located on the east coast of South Africa, within the Nelson Mandela Bay Metropolitan Municipality. This dynamic tidal system is a vital nursery for marine fish species and a popular destination for recreational angling. The estuary's health is a primary concern due to historical over-exploitation of its fish stocks, leading to active management discussions aimed at balancing recreational use with sustainability. The surrounding landscape is characterized by coastal plains, sand dunes, and proximity to the Addo Elephant National Park, offering a unique blend of angling and wilderness adventure.
