Ariadne Street is the southern extension of River Heads Road, running to the tip of the narrow peninsula that forms the village of River Heads, about 18 kilometres south of Hervey Bay.

At this point, the street sits at the confluence of the Susan River and the Mary River to the south-west, with the Great Sandy Strait opening to the east. The location serves as a key access point to the waterways of the Great Sandy Strait region.

Nearby facilities noted on navigation charts include a barge ramp and boat harbour, and the area is the departure point for vehicular barge services to the World Heritage-listed K'gari (Fraser Island).

The surrounding waters are shared by the Mary and Susan River system, and boaters are advised to navigate with caution in this area.
