This heavily trafficked, well-marked trail starts from the car park at the end of Lower Portals Road in Mount Barney.

The trail makes its way through undulating terrain under towering eucalypts and among brush box trees, other natives and grassland.

The track is found in the foothills of Mount Barney and you can peak views of the imposing mountain through the tress at various points of the walk.

While there are few prolonged ascents, there is a decent amount of elevation gain on the walk, with short moderate to steep sections (some with steps) followed by descents and the odd plateaued section. The track is also quite rough in sections.

There are a number of creek crossings on the way, with Rocky Creek and Mount Barney Creek the most prominent. In wet conditions some other smaller creeks may start to flow.

Just prior to Mount Barney Creek you will pass through a metal gate/fence. Make your way to the creek and locate the small directional sign on the opposite side of the creek – this is the best place to cross Mount Barney Creek.

From there, head left – upstream – to the Lower Portals. To reach the portals, you will have to squeeze up, through and over some large boulders.

The portals are pristine and set within a rocky gorge, with water cascading over rocks into the pools. The crystal-clear water starts shallow, but there are some deep sections. It is the perfect place to cool down after the walk.

Track: Graded and well-signed, the track is relatively easy to follow, with some rough sections and steps.

Difficulty: The track requires a moderate level of fitness. While not a particularly long track, there is a lot of undulation and elevation gain. The track is also rough in sections, with many exposed rocks and tree roots, so care is needed. Care is also needed at the creek crossings, particularly after recent rain, where the creek can become flooded and the rocks slippery.

Direction: This is an out-and-back track that returns the way that it came.
