About the Walking Trail

The River Loop is sometimes known as the “North Warren Reservoir Reserve Loop”, “East Warren Reservoir Loop” or “Eastern Loop.”

A short drive south east of Williamstown in the Barossa Valley is Warren Reservoir Reserve. Here you can explore by foot or mountain bike along two trails, or bring your kayak and paddle the waters.

Trailhead Signage

Signage at the carpark trailhead may not reflect the new named, waymarked trails. We expect carpark trailhead signage will be updated during 2024.

Once you start walking, the trail is well marked along the way with coloured, named waymark signs.

About the River Loop, Warren Reservoir

The River Loop starts at the Warren Reservoir Southern Car Park (Old Bridge Hub – of the two carparks, this further from to Williamstown and closer to Mt Pleasant.)

After crossing the Old Bridge, it meanders through plantation forest, redgums, blackwoods and silky tea tree communities. Watch for yellow-tailed black cockatoos and enjoy the sound of the wind whistling through the pines.

The River Loop is an unsealed trail following fire and access tracks. The trail is shared-use for walkers, runners and mountain bikers, so respect other trail users.

There are picnic shelters and accessible toilets located in the carpark.

Getting there

Start the trail from the Warren Reservoir Southern Car Park (sometimes called the Old Bridge Hub), located off of Warren Road (B34), Mount Crawford SA 5351, 7km south of Williamstown, south of the road bridge over Warren Reservoir. Of the two carparks, this further from to Williamstown and closer to Mt Pleasant.
