O'Shannassy Aqueduct Trail

The O'Shannassy Aqueduct Trail is 34.27 km long with 1,218 m of elevation gain, so it is usually best treated as a multi-day hike rather than a short day walk. Most hikers break it into 2 days, especially when walking the full route through Yarra Ranges National Park between Don Valley and East Warburton.

The O'Shannassy Aqueduct Trail runs through Yarra Ranges National Park from Don Valley to East Warburton. One established access point is the Yuonga Road Carpark in Warburton, and the trail also has key access points around Dee Road in Millgrove, where parking is available for walkers using shorter sections or car shuttles.

The O'Shannassy Aqueduct Trail is generally rated medium difficulty. While much of the aqueduct alignment is on a gentle grade, the full hike still covers 34.27 km and climbs 1,218 m, and some access points from the valley floor are steeper and more demanding than the main aqueduct track itself.

Full access has been restored along the O'Shannassy Aqueduct Trail. Parks Victoria states that the previous closure between Dee Road in Millgrove and Sussex Street in Warburton has been lifted, and the repaired Dee Slip Bridge reopened in April 2026 after works that began in late 2025.

Yes. The O'Shannassy Aqueduct Trail has several access points that make shorter out-and-back walks possible instead of committing to the full 34.27 km route. A commonly noted easier section is between Dee Road, Millgrove and Yuonga Road, Warburton, where the trail stays almost level for several kilometers.

The O'Shannassy Aqueduct Trail passes through Yarra Ranges National Park, and dogs and other pets are not permitted in that park. That means the trail is not dog-friendly for the national park sections between Don Valley and East Warburton.
