Smith Creek Falls is a small cascades hidden deep within the Paluma Range National Park. It lies about 14 kilometers south of the Paluma township. The track following an old logging road for ten kilometers before following a ridge down to Smith Creek for another four kilometres. This track is being recut by National Park Volunteers (namely Wilfred and Jamie) to Smith Creek Falls. Although this is newly maintained trail, good navigational skills are necessary.
Park your car as if you are going to McClellands Lookout. Walk down Mt Spec Road passing the revegetation site on your left (Note that Cloudy Clearing Mine is on the opposite side of the road) until you reach the PRB trailhead. Follow the old logging road for about 10 km. From here, the trail is a bit harder to follow. Foller the rideline down, passing through a gully and then down into Smith Creek.
Once you arrive at Smith Falls, you can take a refreshing swim and refill your water - it is recommended to treat your water. There are also room for about two small tents and several hammocks. This hike makes for a secluded, overnight, weekend trip away.
The trail continues southward along the PRB Track however, this is unmaintained and required excellent navigational skills as the old PRB Track is hard to follow. The logging operations were shutdown before they could connect the north and south logging roads together leaving a ten kilometres stretch of bush bashing.
If you are inclined to travel southward along the PRB Track, Ollera Valley Lookout is a great sight to see but note, there has never been a trail cut to it so no marker will be seen.
