Snorkeling Information and Map
With its perfectly calm and always crystal-clear water, Greens Pool in the William Bay National Park is superb for snorkeling. Beneath the calm surface of the water there’s an underwater world of fish, seaweeds, starfish, anemones and sponges waiting to be discovered.
Because the water is so reliably clear, even on a cloudy day you won’t be disappointed snorkeling at Greens Pool.
The only limitation is the freezing cold temperature of the water, especially when the weather is also cold! If you want to stay out snorkeling for longer than 20 minutes or so, you really do need a wetsuit!

Click here to follow along with my underwater photos from when I went snorkeling at Greens Pool in summer. All the photos on that page were taken within about half an hour so you can really see the diversity of marine life present in Greens Pool. All the most common species are there, except perhaps sting rays which I did not see that day but have seen in the past.
Or, continue reading this page to find out my recommended routes to take for your own Greens Pool snorkeling adventure :-).
Where to Snorkel in Greens Pool
Greens Pool Snorkel Route 1
For an easy short snorkel, walk west about 200m along the beach and enter the water where the innermost line of off-shore boulders meets the beach.
Swim following the line of rocks eastwards into the middle of Greens Pool. Swim back to shore via the flat-topped rock that kids like to jump from, and the big rock close to the beach.
This swim is fairly suitable for kids because it’s well protected from waves, and the deep seafloor rises up to form shallow sandbanks around many of the rocks. At its furthest point, it’s 150m from the beach.
When the ocean is calm enough, you can extend the snorkel by swimming out to the line of rocks further out, or crossing over to the headland and following it around to the east.
Greens Pool Snorkeling Route 2
An alternate route to take us to begin your snorkel in the eastern corner of the beach, then follow the headland out and around to the left. There are some small beaches in amongst the rocks where it’s very easy to get in and out of the water, which comes in handy once the water starts getting too cold.
If you want a shorter snorkel you might prefer to jump off the rocks further out or enter the water from the little beachlet in amongst the granite.

What will you see while Snorkeling at Greens Pool?
The granite headland and boulder-islands form the an interesting backdrop to the underwater scenery at Greens Pool. Seaweeds and sponges grow around the rocks, providing an environment favoured by fish such like zebrafish and old wives, and if you look closely you should be able to spot a starfish or two.
Here’s a list of some of the most common fish species at Greens Pool:
- King George whiting, especially in the open sandy areas
- Zebrafish are extremely common, even in the shallows – most often seen congregating amongst the seaweed that growing on the rocks
- Moonlighters – these distinctive black and white striped fish are seen very frequently at Greens Pool and elsewhere along the South Coast of Western Australia. Juvenile moonlighters are very pretty.
- Bullseye, usually seen schooling under ledges
- Old wives – they less common at Greens Pool than at some other South West snorkelling sites, but you’re still highly likely to see at least one or two, especially if you dive down and look under ledges at the base of the rocks.
- Senator wrasses
- Bream, especially silver drummers
- Orange starfish on the rocks
