Lagoon landscapes offer some of the most reliable summer picnic settings in Southern Africa.

They combine calm water with natural shade, soft sandbanks and sheltered inlets. These environments are less exposed than open beaches and provide visitors with predictable comfort even during peak season. The following guide highlights key lagoon areas that deliver accessible picnic sites, scenic views and the kind of relaxed atmosphere that suits families, couples and solo travellers.
Knysna Lagoon, Western Cape
Knysna Lagoon remains one of the most versatile lagoon environments in the region. The tidal system provides broad, shallow areas that allow long and comfortable picnics. Bollard Bay on Leisure Island is the most suitable space for visitors who want safe swimming conditions and easy access to shaded areas. The lagoon supports diverse birdlife, especially wading species that feed along the mudflats during low tide. Travellers can combine a picnic with short boat excursions that operate from the nearby waterfront, which introduces additional opportunities for sightseeing.
Kosi Bay Estuary, KwaZulu Natal
The Kosi Bay estuary system is known for its high water clarity, stable temperatures and natural tranquillity. The lagoon edges near the third lake provide firm sandbanks that make it simple to arrange picnic seating. These areas are surrounded by mangroves and indigenous vegetation, which create pockets of shade throughout the day. The system supports a range of aquatic species, making it a popular site for low impact snorkelling. Visitors must remain within designated areas because the region falls within the iSimangaliso Wetland Park and is managed according to conservation guidelines.
St Lucia Estuary, KwaZulu Natal
The St Lucia estuary offers structured picnic facilities that allow safe and organised access to one of the largest estuarine systems in Africa. Elevated picnic zones provide clear views of the water without interfering with resident hippos and crocodiles. The area forms part of a protected wetland network and provides essential habitat for migratory birds. Visitors can use the picnic areas as a base for short walks, birdwatching or guided excursions into the broader park. The facilities include shaded seating, clean restrooms and well maintained pathways, which support a comfortable visitor experience.
Walvis Bay Lagoon, Namibia
Walvis Bay Lagoon functions as a key birding area on the Namibian coast and offers expansive views over shallow tidal water. The lagoon is recognised as a Ramsar site due to its ecological importance. Its promenade includes several informal seating areas where travellers can set up picnics while observing flamingos and other shorebirds. Morning conditions usually provide the most stable weather, with weaker wind and cooler temperatures. The lagoon’s proximity to the town centre also makes it convenient for travellers who want quick access to food outlets and public facilities.
Inhambane Lagoon, Mozambique
The Inhambane lagoon system is characterised by warm, shallow water and gently sloping banks, which make it suitable for relaxed swimming and extended picnics. The surrounding vegetation includes palm trees and coastal forests that provide natural shade, and the lagoon’s layout offers sheltered spots during most weather conditions. Many local lodges prepare picnic baskets for day visitors, which simplifies planning for travellers who do not want to transport their own supplies. The clear water also supports low impact water activities such as paddling and casual snorkelling in specific areas.
Sedgefield Lagoon, Garden Route
Sedgefield Lagoon is one of the quieter tidal systems along the Garden Route. It appeals to visitors seeking predictable swimming conditions and uncrowded banks. The picnic zone near the river mouth is popular because the water remains shallow for long periods during the tidal cycle. Canoe and stand up paddleboard rentals are available for visitors who want an additional activity beyond the picnic setting. The lagoon is located close to local markets and food vendors, which makes it easy to extend a day trip with additional stops.
