Stand on the footbridge at Bells Rapids in August and you’ll feel the spray before you see the water. The Avon River, swollen from winter rain, punches through a gap in the Darling Scarp and turns into proper whitewater, loud enough to drown out conversation. Come back in February and you’ll find the same footbridge over a lazy trickle, kangaroos grazing where kayakers were fighting current six months earlier. Bells Rapids is a different place depending on the month, and getting that timing right matters more here than at almost any other Perth day trip.
The park sits on Cathedral Avenue in Brigadoon, on Whadjuk Noongar Country, about 40km northeast of Perth CBD, managed by the City of Swan. There’s no entry kiosk, no gift shop, no manicured infrastructure, just a gravel car park, a toilet block, grassy picnic areas and a footbridge over the rapids themselves. What you’re paying nothing for is a legitimate whitewater spectacle for a few months of the year, two solid walking trails, and a front-row seat to one of WA’s oldest endurance races.

Who will Enjoy Bells Rapids
Families and casual walkers do well on the River Walk, a flat 2.5km path that hugs the riverbank without any real climbing. Fitter walkers and photographers get more out of the Goat Walk, a steeper 3km route with a proper scramble up the scarp face and the better vantage point over the rapids. Combine both and you’ve got a 5.5km circuit that takes most people around two to two and a half hours. Dog owners do well here too. Kangaroo spotters should come at dawn or dusk, when western greys graze the open grass near the car park.
It suits you less if you’re chasing a swimming hole or visiting outside June to September. The river drops to a trickle by summer, and the currents that remain are dangerous, not a look-don’t-touch inconvenience but an actual hazard. If you want water you can get into, Serpentine Falls is a better bet.
The Rapids and the Trails
The rapids form where the Avon River meets the edge of the Darling Scarp, and the sudden change in elevation forces the water through a narrow, rocky channel. In winter and spring that’s a spectacle. By late spring the flow starts dropping off, and by summer the rapids are often reduced to bare rock. A footbridge crosses the river right at the rapids, with a viewing platform that puts you close enough to feel the spray during a good winter flow.
There are two official trails, both starting from the main car park, and they combine into one longer circuit:
- River Walk: 2.5km, about an hour, easy. Follows the riverbank on mostly flat terrain. Good for families, dog walkers, prams on the drier sections. One of the better vantage points for watching the Avon Descent in August.
- Goat Walk: 3km, about 90 minutes, moderate to hard. A steep climb up the scarp with some rocky, uneven sections, rewarded with panoramic views over the rapids and the Swan Coastal Plain toward the coast.
Do both and you’re looking at a 5.5km combined circuit, roughly two to two and a half hours depending on how many photo stops you make. The bushland along both trails is Darling Scarp habitat: wandoo, flooded gums, swamp paperbark and swamp sheoak overhead, with acacia, grevillea, hibbertia and grass trees (xanthorrhoea) flowering at ground level through spring. Black cockatoos, ring-neck parrots (“28s”), honeyeaters and willy wagtails are common along the trail, and quendas (a small native bandicoot) turn up in the undergrowth if you’re quiet.

The Avon Descent
The Avon Descent is a 124km, two-day whitewater race held every August, running from Northam to Bayswater: 55km from Northam to Toodyay on day one, then 69km from Toodyay down to Bayswater on day two. Bells Rapids sits roughly at the halfway point of the full course, which makes it one of the better-known spectator spots, not the finish line. Paddlers and power boats come through the rapids in a steady stream over several hours, and it’s a social atmosphere: spectators camped on the grass, kids running around, everyone watching competitors try to read the water correctly.
If you’re coming specifically for the Descent, arrive early (by 8am) to get parking and a decent spot near the footbridge. It’s free to watch. Check the Avon Descent website for the exact date each year, since it shifts within August depending on the calendar.
Seasonal Timing
- June–August (winter): Peak flow, the rapids at their most dramatic. Cool and often wet (12–18°C). The Avon Descent runs in August. This is the best window for the whitewater itself.
- September (spring): Flow is still reasonable early in the month and wildflowers start appearing along the trails. Mild, pleasant walking weather.
- October–November: Flow drops off noticeably. Still a decent bushwalk, less of a whitewater destination.
- December–February (summer): Often close to dry. Hot (up to mid-30s). Come for the walk, not the water, and go early to avoid the heat.
- March–May (autumn): Flow starts rebuilding after the first rains. Mild and quiet, an underrated time to visit if you don’t mind a lighter rapids display.
Local Tips
Arrive before 11am on winter and spring weekends if you want an easy parking spot near the picnic area. The gravel car park has good capacity and rarely turns people away entirely, but on a sunny Sunday in wildflower season you may end up parking further out and walking in. There are no picnic tables or public BBQs on site, so bring your own blanket, chairs and food. Many visitors bring a portable BBQ when fire restrictions allow it. Mobile reception is patchy in parts of the park, so download a map or directions before you leave home.
Dogs are welcome here and it’s a popular dog-walking spot, though keep them under control near the rapids and river edges. If you’re bringing kids, keep them well back from the footbridge railing during high winter flow. Early morning is by far your best chance of spotting kangaroos, which graze the open grass near the car park before retreating to shade as the day warms.
Is It Worth Your Time?
In winter and spring, yes, easily. It’s free, it’s a 45-minute drive, and the combination of whitewater, a decent walk and kangaroo spotting is hard to match for zero dollars. Pair it with lunch or a tasting in the Swan Valley wine region, which sits just south, for a full day out. Outside June to September, treat it as a quiet bushwalk rather than a waterfall pilgrimage, and you won’t be let down.
