Dillon Beach (WA 316) is the central and main bay beach. It occupies the northern shore of the bay, faces south-southeast and curves round for 6.7 km between an eastern 50 m high headland and a protruding 30 m high bluff that separates it from beach WA 317. The beach receives relatively high waves averaging over 1.5 m for most of its length, the wave decreasing slightly towards the west. The waves break across a 300 m wide double bar systems along the eastern-central section, with rips dominating both bars. Towards the west the surf zone narrows to an 80 m wide single bar, also cut by rips every few hundred metres. Massive active and vegetated transgressive dunes extend northeast from the beach reaching up to 3.5 km inland and to height of 60 m. These decrease in width to the west, where Bitter Water and a second creek drain through the dunes and across the beach. A 4WD access track follows Bitter Water Creek to the shore. read more
