Snorkeling here explores the shallow, estuarine waters of the Tamar estuary, where the river meets Bass Strait. The shoreline is rocky in parts with sandy patches, offering a unique mix of estuarine and marine species. Historically known as Green Island, this site was used by early European settlers and today offers a scenic, remote-feeling snorkel right off the dirt road access.
