West Mount Barren is accessible by an unsealed road suitable for 2WD vehicles that runs off Pabelup Drive.

A carpark with a plaque at the base of the mountain marks the beginning of a track that is an easy two hour return walk to the summit.

Visitors are encouraged to stay on the footpath so as to minimise the spread of dieback which is a threat to the native plants of the area.

[1] The vegetation surrounding West Mount Barren is best described as scrub-heath with many types of shrubs that thrive in the quartzitic or lateritic sand, often in rocky situations.
