Mt Trio comprises three peaks and was once known by its Aboriginal name Warrungup, meaning "three become". The trail ascends steeply from the parking area via many steps to a saddle between the east peak and the north peak. The track then follows a more gentle slope to the highest (northern) point at 856 metres. There are excellent views from the top when the weather is clear.

More than 1500 species of flowering plants exist in the Stirling Ranges,representing almost 40 percent of the known flora of the south west. Approximately 80 species grow nowhere else in the world. Mt Trio is known for its bright red mountain bell, Darwinia lejostyla.

A very good walk, although the first 500 m is not for the fainthearted. A good alt name would Mt ManySteps. The initial climb is very steep and should not be accomplished too fast as you WILL tire before you reach the saddle. The last portion of the walk is quite comfortable towards the peak. As with most summits, a rock cairn marks the summit. This time of the year the flowers and the views are absolutely wonderful. We wanted to hike to the second and third peaks and we found a path leading off south just at the top of the climb. It was quite hard to follow, very overgrown but does take you to the other peaks, one is a huge rock and one a summit similar to the main peak. All in all, this hike is a very good one and as with all Stirling Range walks, very satisfying to complete.

Great views from the the top. Recommend walking sticks as some of the steps are rather high for vertically chanllenged people like myself.

Supported by great organisations

Trails are free and bring so many benefits to our community by providing opportunities to have fun, get fit, socialise, explore and challenge yourself. But they also have to be managed and maintained which only is made possible through terrific sponsors, donations and/or volunteering.
