The Sundays River is a substantial tidal estuary flowing into the Indian Ocean at Algoa Bay, near the village of Colchester within the Nelson Mandela Bay Metropolitan Municipality. The primary access point for paddlers is in Colchester, where commercial operators like Sundays River Adventures and Joe Bananas Kayak Tours are based, offering canoe and kayak rentals and guided trips. A specific launch location is referenced near the restaurant "A Taste of Africa" and a Kwikspar supermarket. The river empties into the ocean, and paddlers can head towards the Sundays River mouth, which opens into Algoa Bay. The surrounding landscape is dominated by the Alexandria Coastal Dune Field, the largest and least degraded coastal dune field in the southern hemisphere, with some dunes noted as among the highest in South Africa. These dunes and the adjacent Woody Cape Nature Reserve, which is part of the Addo Elephant National Park, provide a dramatic backdrop. The area supports significant birdlife, with many species feeding in their natural habitat along the river. The river is noted for its green and grassy banks despite the arid regional terrain. The overall character is that of a scenic, biodiverse estuary flanked by massive dunes, offering a blend of river and near-coastal paddling with potential views of the bay from the dune peaks.
