Shallow reserve rock for easy snorkel and scuba.
Shag Rock is a shallow Goat Island reserve dive with easy shore access, kelp-fringed rock, and sandy channels that suit beginners and snorkellers on calm high tides. The site is popular because fish gather around the rock and the surrounding reserve supports a lot of life. Plan it around tide, wind, and boat movement; the rock itself changes character as the water rises and falls.
