The Mackenzie River/Bun-nah Trail is a historic 10.5km Grade 3 hike located within Grampians National Park, Victoria. This route, suitable for walkers and mountain bikers during dry conditions, takes approximately 3 hours to complete.
The trail can be accessed from either Wartook Valley or Zumsteins Picnic Area. If you're aiming to continue onwards to Mackenzie Falls after your Bun-nah Trail experience, starting at Wartook Valley is recommended. This section adds an additional 3.7km to your journey.
Originally known as the Back Track, this path follows the scenic Mackenzie River, named Bun-nah by the traditional Jadawadjali people. Interpretive signage along the way details the area's rich history and cultural significance to the Jadawadjali people.
Be mindful that the Mackenzie River can flood at times, rendering the trail impassable. If you encounter high water levels, access the trail from the alternative starting point at Cooinda Burrong.
For over a century, the Back Track served as the main route from Wartook Valley into the heart of the Grampians. It was used by walkers, horses, carriages, and even bullock wagon teams transporting supplies, livestock, timber, and local produce like honey and beeswax.
The Bun-nah (Mackenzie River) holds a special place in Jadawadjali culture, flowing through their land and featuring prominently within the Gariwerd Creation story, alongside the Walla Walla (Wimmera River). As you traverse this path alongside the Bun-nah, you're essentially walking amongst the steps of this creation story.
History
For 100 years, the 'Back Track' was the main road from Wartook Valley into the Central Grampians Ranges. The Back Track was traversed by walkers, horses, carriages and bullock wagon teams. The track was used to transport supplies, animals, timber from mills, tannin bark from wattle stripping and honey and beeswax collected by local beekeepers. Bun-nah (Mackenzie River) runs through Jadawadjali country, from the northern part of Gariwerd down through the plains to its confluence with Walla Walla (the Wimmera River) at Horsham. Both rivers form a key part of the Gariwerd Creation story. As you follow the track along Bun-nah, you are following the creation story of Tyingal (Tchingal) the emu and Waa the crow.
At times the Mackenzie River floods and the trail is impassable; in this instance it is best to access the trail at Cooinda Burrong.

Getting to the trailhead in Grampians National Park.
Wartook Valley runs along the Grampians’ western foothills, giving a completely different perspective of the mountains. Heading to or from Horsham, this is the scenic alternative to the Western Hwy (A8). From Wartook, the sealed Roses Gap Rd and Mount Victoria Rd pass through the park, and there are lots of unsealed roads and tracks passing little creeks, waterfalls and idyllic picnic spots.
This trail reopened in 2018 so the GPX file may not be completely aligned with the newly aligned trail.
