Blue Mud Bay is a vast, shallow, partly enclosed bay on the remote eastern coast of Arnhem Land, facing Groote Eylandt across the Gulf of Carpentaria. Spanning 90 km in length and up to 35 km wide, its inner coastline is a mosaic of small bays, inlets, headlands, and islands bordered by intertidal mudflats, mangroves, and freshwater floodplains. Snorkelers exploring the sandy shallows and rocky headlands can experience one of Australia's most pristine and culturally significant coastal environments — the bay was the site of the landmark Blue Mud Bay sea rights case. The surrounding Laynhapuy Indigenous Protected Area protects this wild, untouched landscape. Access is restricted; permits from the Northern Land Council are required.
