Geltwood Beach is located within Canunda National Park in South Australia, approximately 300 meters from the ocean. It is known for its high-energy waves, making it unsafe for swimming. The beach is part of a larger coastal region featuring diverse habitats and offering opportunities for bushwalking, birdwatching, and exploring limestone cliffs and dunes. The area is rich in Aboriginal cultural significance, with remains of the Boandik people visible throughout the park.
Visitors can enjoy scenic drives or four-wheel driving through the park's vast sand dunes and along the beach. However, the high-energy conditions make it more suited to activities like surfing and fishing rather than swimming.
Geltwood Beach is accessible by 2WD vehicles, and nearby camping facilities provide an immersive experience of the natural surroundings.
