The Walk
The Spinebill Loop is the starter at Myponga Reservoir Reserve — the reserve’s shortest bird-named trail and the natural choice if you’re stopping at Myponga on the way south to the coast, walking with small children or simply want a quick break with a proper water view.
At 700 metres on flat, well-maintained formed gravel trail, it’s a fifteen-minute round trip to the Reservoir Lookout and back. The climbing is almost nonexistent — about 18 metres of gentle undulation — and the surface is reliable underfoot year-round. That simplicity is the point.
What You’ll See
From the Eatts St car park the trail runs gently across the edge of the reserve to the Reservoir Lookout, an open viewpoint across the Myponga Reservoir water storage. The reservoir sits in a horseshoe of rolling hills — farmland and native bush on the higher slopes, the water still and reflective below. On calm mornings the views across the water are quietly beautiful.
The reserve attracts good birdlife precisely because it’s low-traffic. SA Water reserves tend to be undervisited relative to national park walking areas, and Myponga is no exception. Even on the short Spinebill trail it’s worth slowing down at the lookout and watching the margins of the reservoir for water birds.
Practical Notes
Toilets and parking are at the Eatts St car park — use the toilets before setting off, as there are no facilities out on the trail. No dogs are permitted anywhere in the Myponga Reservoir Reserve.
