Treat this as a serious remote walk, not a swim stop you can add from the car. A listed Telegraph Junction–Waterloo Bay–Little Waterloo Bay return covers 23.6 km and is Grade 4; the full Southern Circuit takes three to five days, with the bay used as a camp stop on a popular itinerary. Those details are route choices, not the distance to the beach alone. Bring what the walk requires: no bay-specific food, toilets, drinking water or parking were verified. Little Waterloo Bay and its hike-in campsite are separate destinations farther north, and their amenities or current access conditions do not describe this beach.
