The Sandy Point Sanctuary Zone within the Shark Bay Marine Park offers a sheltered snorkelling area on the eastern side of Dirk Hartog Island in three to four metres of water. Here, numerous species of blue, purple, green and brown staghorn corals grow in a great diversity of forms. In one area there is a virtual garden of beautiful blue staghorn coral. Brain corals and plate corals can also be seen.
Diving and snorkelling in the Shark Bay Marine Park should only be done on a slack tide. Take care not to anchor on fragile corals. Stay alert for boat traffic.
