Do the whole trail as day walks (with a car shuffle), trek the whole trail and camp along the way, or walk selected day walk sections. The walking takes in magnificent coastal scenery including sheltered bays, offshore islands, mobile sand dunes and beautiful beaches. The trail is generally easy walking through coastal heath, mallee and along beaches.

Extend the walk a further 26km to the north outside the park, following the Parnkalla Trail via Tulka into Port Lincoln or on to North Shields.

These are only recommended for very experienced and fit walkers with specialised skills, including navigation and emergency first aid. Tracks are likely to be very rough, very steep, and unmarked. Walks may be more than 20 kilometers. These challenging walks demand a high level of fitness and experience to navigate difficult terrain, significant elevation changes, and potentially unformed paths.
