The boat ramp at Ariadne Street sits at the southern tip of the River Heads peninsula, where the Susan River meets the mouth of the Mary River before opening into the Great Sandy Strait.

Ariadne Street is the southern continuation of River Heads Road as it reaches the end of the peninsula, placing this launch site in a sheltered position convenient for boaters heading into the Strait.

The surrounding waters require careful navigation, with features such as Buttenshaw Bank and Black Rock nearby.

Volunteer Marine Rescue Hervey Bay and Coast Guard Sandy Straits both monitor the area during daylight hours, providing an added layer of safety for recreational boaters using this ramp.
