Marmong Point boat ramp is located on Nanda Street, Marmong Point, on the shores of Lake Macquarie in New South Wales. The concrete ramp is rated in good condition and accommodates two lanes, making it suitable for a range of vessel sizes.

Tidal variation on the lake is minimal, providing relatively stable water levels for launching. The ramp features a gradual slope with good water depth, though occasional submerged debris may accumulate near the ramp edges.

An adjacent timber jetty, approximately 15 metres long, can fit up to two boats. Parking is available nearby on gravel and grass surfaces, though spaces can be limited on busy weekends. Use tends to be quiet on weekdays with moderate traffic on weekends.
