Mimosa Rocks National Park stretches 20 km along the wild Sapphire Coast between Tathra and Bermagui, offering a string of pristine ocean beaches, protected coves, and calm lagoon systems perfect for snorkeling. Moon Bay is the standout — a sheltered cove with clear waters and fascinating rock formations. Aragunnu Beach, Middle Beach, and Gillards Beach each provide unique underwater terrain around the park's iconic folded Ordovician rocks and sea caves. Nelson Lagoon offers calm, protected paddling and snorkeling away from ocean swell. The park's name comes from the 1863 wreck of the paddle steamer Mimosa, and remnants can still be seen at low tide near Aragunnu.
