The Falls and the Rock Pool
Serpentine Falls is a cascading 15-metre waterfall that tumbles into a large, granite-fringed rock pool. The setting is striking: the waterfall’s flow depends entirely on seasonal rainfall, with the most impressive displays after winter rains. The rock pool itself invites swimming, though water quality is a critical consideration.
Important water quality note: Swimming was prohibited in December 2024 due to poor water quality and detection of Naegleria fowleri (a brain-eating amoeba). Before entering the water, check the current water quality status with the Department of Biodiversity, Conservation and Attractions (DBCA) or visit https://alerts.dbca.wa.gov.au/ (go to “List View” and look for the search bar and type serpentine) for real-time alerts. The Shire of Serpentine Jarrahdale conducts regular microbiological testing and assigns swimming grades to the site. Always verify current conditions before planning to swim.
The surrounding granite landscape offers excellent photo opportunities, and visitors consistently mention the unexpected joy of seeing kangaroos grazing in the picnic area. As many visitors tell us, “we absolutely loved the kangaroos that live around the picnic area, up close wildlife we hadn’t expected.” The peaceful atmosphere, particularly on weekdays, makes this a rewarding blend of natural beauty and accessibility.

When to Visit
Serpentine Falls changes dramatically with the seasons. Choose your timing based on what you want from the experience.
Spring (September to November): This is the best overall time to visit. The waterfall flows impressively from late winter rains, wildflowers are in full bloom throughout the park, and the weather is warm and dry. Expect moderate to high crowds on weekends, but this is also when the park truly shines. Hundreds of native wildflowers bloom between late winter and spring, with peak display from July to November.
Summer (December to February): Water temperatures are warmest, perfect for swimming once water quality permits. However, the waterfall flow reduces significantly during dry spells and may dry up entirely. Heat stress is a concern on exposed rocks with limited shade. Crowds reach peak levels, especially on weekends and school holidays; the park typically closes to new visitors by 9-10 am on busy days. Arriving early before 10 am makes all the difference.
Autumn (March to May): Pleasant temperatures suit walking and picnicking. Waterfall flow is moderate and steady from autumn rains. Crowds are more manageable than summer, though still busy on weekends. This is an underrated time for a peaceful visit.
Winter (June to August): The waterfall reaches its highest flow after winter rains, delivering the most impressive views. Swimming is not recommended due to cold water, slippery rocks, fast-flowing currents, and dangerous depth variations. However, it’s ideal for photography and hiking in peaceful conditions with lower crowds, except during school holidays.
Getting There
Serpentine Falls is 55 km southeast of Perth, approximately one hour’s drive. There is no public transport access; you must drive. From Perth CBD, head towards the Perth Hills via the Brookton Highway (State Route 1), following signs towards Serpentine and Jarrahdale. The main picnic area car park is well signposted.
The gravel car park at the main picnic area has limited capacity. On busy weekends and school holidays, it fills quickly, often by 9-10 am, and the park closes to new visitors once full. Arriving early significantly improves your chances of entry. Weekday visits avoid this constraint entirely and offer a calmer experience.
Designated accessible parking bays are available at the main picnic area for visitors with mobility needs.
What to Bring
- Sun protection: The granite pool area offers limited shade. Bring a hat, sunscreen, and sunglasses, especially in summer.
- Footwear: Wear shoes with good grip. The rocks surrounding the pool are extremely slippery when wet, creating a high slip hazard.
- Water and snacks: Bring plenty to stay hydrated, especially in hot weather. There are no on-site cafes or shops.
- Picnic food: Pack lunch if you plan to stay for several hours. The picnic facilities include BBQs and tables. There’s no café.
- Swimwear and towel: If you plan to swim, bring these. Always check the current water quality status first.
- Camera: The landscape offers excellent photo opportunities, especially in early morning light or after winter rains.
- Insect repellent: Particularly useful in warmer months.
The nearby township of Serpentine has local shops and cafes where you can buy supplies before or after visiting the falls.
