Secret Bay boat ramp is a single-lane concrete ramp located on Letchworth Parade in Balmoral, on the western shore of Lake Macquarie. Rated in excellent condition, it provides direct access to the lake's waters, including the nearby bays of the area.

The ramp is accompanied by a timber jetty running parallel to it, aiding in the safe launching and retrieval of vessels. It is well sheltered from most wind directions, making for a calm and manageable launch environment.

The surrounding area is quiet and residential, and moderate parking is available for vehicles and boat trailers, with wheelchair-accessible parking and entry.
