Peet's Falls is a waterfall tucked away in the Goldsborough Valley near Cairns, Queensland, set along the Mulgrave River corridor at the foot of the Gillies Range. The falls feed a beautiful swimming hole that rewards those who make the trek out to see it.

The walking track is a couple of kilometres long, worn and generally easy to follow, though it includes some steep sections and at least one creek crossing. Hikers should wear sturdy footwear.

The valley sits noticeably warmer and more humid than the Atherton Tablelands above, so visitors should come prepared for tropical conditions. The falls are not signposted, so some prior research is helpful before heading out.

Total hiking time can run around five hours return.
