Marion Bay

Marion Bay is a small coastal town at the southern tip of Yorke Peninsula in South Australia, overlooking Investigator Strait. It is known for its long sandy beach, historic jetty, and as the main gateway to Innes National Park. The town serves as a base for fishing, boating, swimming and bushwalking, with accommodation, a caravan park and general store supporting visitors exploring the surrounding coastline and national park.

Visitors can expect a quiet coastal settlement with a wide sandy beach, a timber jetty popular for fishing, and calm to surf-exposed waters depending on conditions. The foreshore has a boat ramp, caravan park and limited shops. The town is the entry point to Innes National Park, with access to rugged cliffs, walking trails, surf beaches and historic sites like Stenhouse Bay and the Inneston ghost town nearby. The setting is natural and low-key, suited to beach walks, fishing and nature-based sightseeing.

Marion Bay is named after the barque Marion and developed as a small port and fishing settlement on southern Yorke Peninsula. The jetty was built to support fishing and coastal shipping. Nearby Inneston within Innes National Park was a gypsum mining town established in the early 1900s, with ruins now preserved as a historic township.

The area lies within the traditional lands of the Narungga people, who have long cultural connections to the southern Yorke Peninsula coastline. Today Marion Bay is valued as a fishing and holiday community and as the service hub for visitors to Innes National Park.
