Accessibility Information
Most of the O'Shannassy Aqueduct Trail is on a gentle grade but getting onto it from the valley floor can be more challenging. However, there are carparks provided at key access points. There are small sections of the trail that are very steep when it crosses roads and converts to a pipeline. The trail has adopted the old service road to the aqueduct for most of the trail and the trail surface is a combination of compacted small to medium sized crushed rock and patches of grass. Small wheeled strollers or small wheeled wheelchairs are not recommended on the trail.
The most accessible section of the Trail is the trail section between Dee Road, Millgrove and Yuonga Road, Warburton. The Trail remains almost level throughout this section. There are no steep gradients and getting onto the trail is much easier. There is a car park at the Dee Road intersection of the Trail that accommodates approximately 16 vehicles. A path of approximately 120 metres of compacted, small crushed rock leads down from the carpark to the Trail. This path is quite steep and it is not recommended for strollers and wheelchairs to use this path to go back up to the carpark.
Due to the steepness of the path leading down to the aqueduct, it is recommended that users in strollers and wheelchairs commence at the Dee Road carpark end of the trail section and car shuffle to finish at another section. The easiest location for getting off the trail is at Sussex Street, Millgrove (a four kilometre stretch). Vehicles are accessed by a path with a slope of approximately 1:10. There are no designated parking bays at the Sussex Street section of the Trail but users can park their vehicles on the side of the road.
The next Trail exit is at Yuonga Crescent, Warburton (an additional three kilometre stretch). The car park at the Yuonga Road section of the Trail accommodates about nine vehicles and is approximately 20 metres from the Trail. There is a short path leading down from the carpark across a bridge over the aqueduct to the Trail. One section of this path has a gradient of approximately 1:10. There is no designated disabled parking at Yuonga Road carpark.
The carparks at Dee Road and Yuonga Road are not suitable for large buses or coaches. This also applies to the Sussex Street access to the Trail.

Some sections of the path are a little steep with a gradient of approximately 1:10.

About the region
Situated between Melbourne and the Victorian Alps, the Yarra Ranges National Park is a place of epic views, majestic rainforest scenery and fun-packed snowplay. Enjoy the panorama from Mount Donna Buang, or go deeper into the park on the Black Spur Drive, and wind through towering Mountain Ash forests to Lake Mountain.
The Yarra Ranges spans an extensive, mountainous area of cool temperate forest around the three towns of Marysville, Healesville and Warburton. This national park is home to the world's tallest flowering tree, the Mountain Ash, which towers over lush tree ferns and mossy Myrtle Beech. Dark gullies are home to clear streams which feed the Yarra River and major reservoirs from which Melbourne draws its drinking water.
The Yarra Ranges boasts some stunning lookouts, one of the best being Mount Donna Buang. From here you can see awesome views of Westernport Bay and Port Phillip - or walk the Rainforest Gallery and see the Mountain Ash from a different perspective. In the winter, Mount Donna Buang is Melbourne's closest winter playground. Many Melburnians have enjoyed their first sight of snow here through the years.
Healesville is the start of the Black Spur Drive, a short but beautiful scenic car journey. The road winds through majestic Mountain Ash forest to Narbethong, passing a number of pleasant walking trails and picnic areas, such as Donnelly’s Weir, Dom Dom Saddle and Maroondah Reservoir Park.

3 Reviews on “O'shannassy Aqueduct Trail Walk (34.5km)”
I think it’s not grade 3 because grade 3 can be up to 20km.
The bridge on the Aqueduct near the Dee Road end is out and has been out for ages due to a tree fall. If you are prepared to scramble down the bank and up again it is still passable but I don’t recommend that for bikes or people wanting a leisurely flat stroll as it is steep and quite a way down and then back up again.
