Top Trail:  Sullivan Rock to Mt Cooke, Darling Range

Overview

This 18.4km return walk on the Bibbulmun Track takes you to the highest point in the Darling Range, Mt Cooke.  A campsite (for walkers only - no vehicle access) is at the base of Mt Cooke so this is also a good option for an overnight walk.

Stunning view

Time stands still while enjoying beautiful views like this on the trail.


About the Trail

This is one of many short walks possible on the Bibbulmun Track which stretches 1000km from Kalamunda on the outskirts of Perth, to the historic town of Albany on the south coast.

This walk starts at Sullivan Rock, just over an hour's drive south of Perth. The Track leading toward Mt Cooke is generally relatively flat. It crosses a broad and interesting creek system and passes through stands of sheoak, banksia and jarrah.

After reaching Mt Cooke campsite the Track ascends 2km to the summit of Mt Cooke, the highest point in the Darling Range, at 582 metres. The view here isn't the best - so continue on past the summit to the southern side of the peak and be rewarded with spectacular views.

If you've decided to stay overnight you can of course set up your tent and leave your pack at the campsite before heading up to the peak.  This is a good overnighter for families with children 8 years and over.  You can find other family hike suggestions on the Bibbulmun Track website.
