Nelson Lagoon is a shallow, pristine estuary on the Sapphire Coast. It is a tranquil and sheltered water body, ideal for calm paddling in canoes, kayaks, or on stand-up paddleboards. The lagoon is a key oyster-producing estuary, indicating healthy, saline water. Its water quality is subject to regular monthly testing by the NSW Food Authority for faecal coliforms as part of a shellfish program. Access for paddlers is informal. The primary launch point is from the Nelson Beach carpark, requiring a short and easy walk to the water's edge. There is no formal boat ramp at the lagoon itself. The lagoon is a popular spot for birdwatching, with species like pied oystercatchers, striated thornbills, and little wattlebirds present, especially in spring. The surrounding area offers spots for informal picnics. The lagoon is connected to the nearby golden sands of Nelson Beach, and the crystal-clear waters are idyllic for a saltwater plunge. The lagoon is part of a coastal walking route where, at low tide, a wade or possible short swim may be required to cross, suggesting a tidal influence on water depth at its ocean outlet. The overall experience is one of quiet exploration in a scenic, natural setting suitable for a gentle paddle.
