The Oyster Stacks are great for fish life. This site should only be snorkelled during a high tide when there is sufficient water over the reef - please check at Milyering Discovery Centre or Exmouth Visitor Centre for tide heights and times.
This site is recommended for more experienced snorkellers. Take care entering the water as the shoreline is rocky with some sharp oyster shelled areas. Enter the water at the end of the walking track and snorkel either north or south.
