Whistlepipe Gully is a 3.5km, grade 3 Circuit hike located in Kalamunda Western Australia. The hike should take approximately 1hrs to complete.


This reasonably easy 3.5km return walk in the Mundy Regional Park follows Whistlepipe Gully in the Perth Hills. The trail follows the narrow river as it courses over cascades and small waterfalls and offers views over the coastal plain to Perth.

Whistlepipe Gully flows down the edge of a large granite formation, running as a waterfall. The section of the trail near the falls is also a superb vantage point from which to see the Swan Coastal Plain, with the city of Perth visible in the distance. Take a picnic and a rug as there are lots of lovely spots to sit by the creek. The trail simply follows stream down one side and returns up the other.  See trail notes below or download the map and walk notes from the Perth Hills Visitor Centre website. A curious feature on this trail is the remains of a house which spanned the falls in the 60’s. It must have been a fabulous place to live but was built without the proper planning permission and had to be demolished. The best time to visit is between June and September when the creeks are flowing or Septmber to November when the wildflowers come out in spring. Park at the western end of Orange Valley Road, Kalamunda. An alternative start point is at the northern end of Lewis Road, Forrestfield. The trail markers are Shire of Kalamunda markers with a pink corner.  Trail NotesnStart point: The end of Orange Valley Road. 1. Leave the car turn around area and walk past the gate and down the right hand side of the creek. Please note: left and right are with reference to the direction of the flow of the creek. 2. Ahead is a bridge across the creek. This is an intersection with the Lewis Road walk. Do not cross the bridge unless you want to do a very short loop in which case cross and walk back up the other side of the creek. 3. You’ll come across the site of a house that spanned the creek in the 1960s. Just downstream from here, cross the creek and then walk back up the other side of the creek to complete the loop.  Alternatively,  continue down the left side of the creek and you’ll reach the Car Park at the end of Lewis Road; the alternative start point; and the downstream intersection with the Lewis Road Walk. 5. Retrace your steps to the crossing just below the old house ruins. Continue up the hill keeping the creek on your left. 6. Do not cross the bridge, continue upstream.  7. Return to the Car Park.
