Nestled in William Bay National Park on Western Australia's stunning south coast, Greens Pool is a crystalline natural swimming enclosure protected from the Southern Ocean by a necklace of smooth granite boulders and islands. The calm, turquoise waters — just 1–3 m deep — make it ideal for snorkellers of all levels. A marked snorkel trail weaves around Bombie Rock and the granite outcrops, where you'll spot zebra fish, wrasse, morwongs, goat fish, western blue devils, colourful sea stars, and the occasional eagle ray or stingaree gliding through the shallows.

Moderate risk: Strong currents
Strong currents can occur at Greens Pool at any time of year, even in the sheltered inner pool area.
Low risk: Slippery granite rocks
The granite boulders around the shore and entry points can be extremely slippery, especially when wet.
Low risk: Stairs access
A long staircase descends from the car park to the beach — can be challenging carrying gear and requires care.
Low risk: Cold water temperature
Water temperatures can drop to around 5–16°C, posing a cold shock risk for unprepared snorkellers.
