Myponga Beach occupies a small valley that has been carved by Myponga Creek and is now partially filled with river and marine sediments forming a flat plain occupied by a few houses and an elongated lagoon and wetland that flows across the southern end of the beach. Houses and shacks line the rear of the beach; so much so a seawall has been built to protect some of the properties. Fifty-metre high grassy bluffs border each end of the beach, with rocks and reefs extending seaward. It is moderately steep and fronted by a narrow continuous bar, with waves averaging about 0.5 metres.
The beach was used as a port and the ruins of the old jetty are still present. Swimming is relatively safe in the sandy central portion of the beach and it is a popular spot for both launching boats and for shore-based fishing off the adjacent rock reefs.
