Akuna Bay Boat Ramp sits on Coal and Candle Creek within Ku-ring-gai Chase National Park, roughly 38 kilometres north of Sydney's CBD, accessed via Liberator General San Martin Drive.

The ramp is a two-lane concrete facility in great condition, with lighting and parking on site. Because it falls within a national park, a park entry fee applies.

The surrounding waters of Akuna Bay are a 4-knot zone, offering calm, sheltered boating away from heavy vessel traffic.

The adjacent marina provides fuel, and the broader precinct includes toilets, BBQ facilities, a kiosk, and a pumpout station, making it a well-equipped launching point for exploring the Hawkesbury River and Cowan Waters.
