Getting there

Type 'Lookout Road, Goomburra' into your GPS.

Pass through Cunninghams Gap on Cunningham Highway. Turn right at Goomburra Rd. Turn right onto Inverramsy Road at the Goomburra Hall and follow this road. The road turns into gravel and crosses the creek a number of times as it passes a number of private campgrounds (Gordon Country). 

When you reach the National Park boundary (signed) take the left branch (Lookout Road). Kurrajong Picinic area is on the right, then cross the creek once more. (This crossing isn't sealed but can handle conventional cars as long as the creek isn't running too high - there is no height sign so pre-walk the creek crossing first).

Araucaria Falls walk is on the left, approx 5km on Lookout Rd.

Route/Trail notes

The trail is very well worn and clear to follow, though being dense rainforest the path can become very muddy after heavy rain.  The first kilometre is level, before you start to descends to the falls.  The trail crosses the top of the falls. Once at the top don't forget to continue up the stairs otherwise you'll miss out on the view.  Once across the other side of the falls, it descends very quickly to the base of the falls. There are exposed tree roots and rock steps used in this section, so on return this may take some time to traverse the ascent.

 Permits/Costs
