William Bay National Park is famous for its turquoise green waters, sheltered bays, windswept headlands and impressive granite boulders.
The Department of Biodiversity, Conservation and Attractions (DBCA) is working with the Wagyl Kaip Southern Noongar Aboriginal Corporation and other key stakeholders to improve visitor access throughout William Bay National Park.
The latest announcement of $3.5 million infrastructure renewal works includes beach access upgrades, a new elevated boardwalk and accessible lookout, and new trail alignments for cyclists and walkers. These works expand on previous investments of more than $5 million since 2019 improving visitor infrastructure at this much-loved destination.
Work completed
- Provision of 182 standard parking bays, five disability parking bays, 10 long-vehicle, 15 motorcycle and two coach bays in the Greens Pool and Elephant Rocks precincts, more than doubling previous parking capacity within the park.
- Sealing of Madfish Bay Road, and Madfish Bay and Waterfall Beach carparks.
- Three new fully accessible toilet and change room facilities at Greens Pool, Elephant Rocks and Madfish Bay.
- Construction of a new 2.6 kilometre shared-use walk and cycle trail between Elephant Rocks carpark and Waterfall Beach, complete with a lookout for spectacular views across Elephant Rocks, Greens Pool, Madfish Bay and beyond to Waterfall Beach. The first 200m of the trail is suitable for wheelchairs and adaptive cycles.
- Upgrade of steps and pathway to access the back of Greens Pool beach.
Current and upcoming work
- New back-of-beach upper-level boardwalk and accessible viewing platform.
- Improved access to Elephant Rocks beach, including sealed pathways, steps and viewing decks.
- Replacement of the beach access steps from Greens Pool carpark to Greens Pool beach.
- While most areas will remain open, Elephant Rocks and Elephant Rocks beach will be closed from 27 July until construction of the new path is complete.
- Planning and design are underway for a new Munda Biddi Trail alignment to remove the cycle trail from William Bay Road and improve the safety of trail users.
- New interpretive signage showcasing the area's natural and cultural values.

Frequently asked questions
Will I be able to visit Greens Pool during the project?
Works have been scheduled to minimise visitor disruption to Greens Pool. Access to Greens Pool will be via the main carpark and existing beach steps during the construction of the back of beach boardwalk. Once this boardwalk is complete, it will provide alternative access to Greens Pool while the main beach steps are being replaced. There may be a short period where no access to Greens Pool is provided. Please note that alternative access routes may be inhibited by severe weather and high tides. Please plan your visit accordingly and check alerts.dbca.wa.gov.au for updates.
Will I be able to view Elephant Rocks during the project?
From 27 July, the access path to Elephant Rocks and Elephant Rocks beach will be closed to complete construction of the new path in a timely manner. Visitors can view Elephant Rocks and Elephant Cove via the lookout located 200m along the shared use trail accessed via Elephant Rocks carpark.
Will the new trails be fully accessible?
Full accessibility to Greens Pool was explored early in the planning process however could not be achieved. Meeting Australian accessibility standards at this site would require extensive ramping which would significantly impact the surrounding landscape, visitor experience and visual amenity. This project does however include the construction of an accessible viewing platform looking across Greens Pool and surrounds.
Why aren't more carparks being built?
The number of parking bays was more than doubled across the park during Stages 1 and 2 of the project. New parking bays and facilities were designed to fit within the existing footprint with little impact to the surrounding landscape. The construction of more parking bays at this point would significantly compromise environmental, cultural and social values.
How long will the project take?
The project is expected to be completed by December. Please be aware that there will be disruptions to access during the winter and spring school holiday periods. Visit exploreparks.dbca.wa.gov.au for alternative places to explore.
