Little Salmon Bay is a serene, south-facing bay on Rottnest Island, sheltered by limestone rocks and grassy dunes that keep the lagoon calm and wind-protected. A 700-metre marked snorkel trail winds through the Parker Point Marine Sanctuary, featuring 10 interpretive buoys that guide you past shallow limestone reefs, vibrant coral gardens, and algae forests. With crystal-clear, never-deep waters, this trail is an underwater classroom — expect to see black scalyfins, Green Moon Wrasse, Western King Wrasse, Western Buffalo Bream, and the occasional Western Rock Lobster sneaking through the seagrass.
