Bournda Lagoon is a coastal lagoon within Bournda National Park on the Sapphire Coast, approximately 14 kilometres north of Merimbula and 10 kilometres south of Tathra. The primary vehicle access and launch point is at the end of Bournda Road, where a dedicated parking area and toilets are located. The lagoon is connected to the ocean via Bournda Beach, and its character is defined by this intermittent opening. Paddling is a promoted activity here, with the water described as ideal for paddling and kayaking, particularly during the summer season. The surrounding environment features paperbark trees, and the lagoon is noted for its scenic, tranquil setting suitable for picnics. A short walking track connects the Tura Beach headland to the lagoon. The park is a natural playground with ocean beaches, creeks, and the larger Wallagoot Lake nearby, though the lagoon itself is a distinct, smaller feature. The overall vibe is one of a protected, family-friendly coastal lagoon within a national park setting. A park entry fee of eight dollars per vehicle per day applies, payable via self-registration. Visitors should check for park alerts before visiting. The lagoon is part of a wetland area that provides valuable habitat, and the park has a rich history of Aboriginal occupation as an important food gathering place.
