About this park
Windswept headlands, large granite outcrops, sheltered bays and beaches, William Bay National Park has something for everyone.
The turquoise green waters combined with the stunning coastline have got folks talking. Enjoy a swim or snorkel in a sheltered bay and explore huge granite rocks. You won’t be blamed for thinking you’re on safari as the rounded boulders resemble a herd of elephants at a watering hole!
During school holidays it’s best to arrive early. The park is popular and parking is limited. Walking is a great way to experience the coastline and the famous Bibbulmun Track passes through the park. There’s so much to see and explore such as rock pools, channels, offshore islands and windswept beaches that attract marine life and shorebirds so be careful where you walk! If you’re lucky, you may spot passing dolphins or whales further out to sea.
Wildflowers are at their blooming best in Spring, but flowers can be found in the park all year round. Lace up your hiking boots and start exploring!
William Bay National Park has picturesque, year-round appeal.
Four-wheel driving is permitted within William Bay National Park only on Mazzoletti Beach, accessible via Parry Beach Caravan Park depending on the sandbar at Parry Inlet.
Snorkel around the boulders in the calm, clear waters of Greens Pool to observe Zebrafish, Stripeys, Banded sweep, Moonlighters, King George Whiting, Leatherjackets, Blackspot goatfish, stingrays, starfish, and many more.
The eastern end of Greens Pool near the access steps is calm, sheltered, and ideal for swimming.
