End of Lewis Rd, Forrestfield


1-2 hrs

Located in Mundy Regional Park in the Perth Hills, the Whistlepipe Gully Trail will leave you feeling like you’ve just discovered an enchanted forest! The scenery on this hike is very pretty with the banks of the gully lined with lush green foliage, paper-bark trees and a variety of wildflowers. Whilst enjoying the sound of the water cascading downstream you will come across a granite outcrop and the ruins of an old house built right on the edge of the gully. These ruins are quite intriguing and definitely make this short family friendly & dog friendly trail very unique!

Whistlepipe Gully is a stunning 3.5km Perth hiking trail that commences at the end of Lewis Rd in Forestfield. There is only a small car park here and in Winter and Spring the trail is very popular so unless you’re early, expect to be parking a couple of hundred metres down the street. As you follow the trail along side the creek you’ll soon reach a giant granite outcrop with water cascading down it on your left, this is a great place to stop and explore as you can get quite close to the water’s edge here and it is very picturesque. After crossing the gully on the bridge you continue down the left hand side of the stream to the ruins.

These old concrete foundations are from the mysterious Wallace Greenham House that once stood here. Wallace Greenham was the outstanding and innovative architect that built this fascinating house in 1963. The house was built in a Japanese inspired style of architecture called Organic Architecture which means to promote harmony between habitation and the natural world. Wallace incorporated the granite boulders in its structure had connecting walkways across the stream.

Descriptions of the house included trees growing up through the floor, sloped roofing with raw timber beams, suspended walkways with the central feature being the rushing water of the stream. It sounded like a mysterious place of beauty and magic surrounded by this magical little valley and the gorgeous Whistlepipe Gully.

From the ruins, continue along the trail for this trails’ steepest and longest ascent (which is about 20m)! From the top turn around to admire your first glimpses of the Perth city overlooking the Swan Coastal Plain. As you follow the trail alongside Whistlepipe Gully you will come across many little trails spur trails that take you to the waters edge and allow you to really immerse yourself in the natural beauty that surrounds you. 

There are two bridges that allow you to cross over and make your hiking adventure shorter if you are with small children or short on time. If you follow the trail right to the end you’ll enter what feels like a rain forest with a deep gorge complete with ancient fallen trees covered in moss and vines. It really is spectacular! The trail loops back around here (near Orange Valley Rd) so you get to experience Whistlepipe Gully and all its beauty from the other side of the banks. You’ll know your peaceful outdoor experience is drawing to an end when you once again see the Perth city skyline as you step out on to a beautiful large granite outcrop. This is the perfect spot for a quiet picnic or to watch the sunset!
