Crystal Cascades is a series of waterfalls and freshwater swimming holes along Freshwater Creek in the Redlynch Valley, roughly 14 kilometres west of Cairns in Far North Queensland.

Set within lush tropical rainforest, the cascades tumble over smooth granite boulders into deep, clear pools, with rainforest canopy keeping the water cool year-round. The creek flows continuously, fed by a large upstream catchment.

A paved walking track of approximately 1. 2–1. 5 kilometres leads past a succession of smaller swimming holes and cascades before reaching the largest waterhole and its main falls at the end of the trail.

The site is popular with locals and visitors alike, though cliff-jumping from the highest point above the main waterhole — known locally as "No Fear" — has resulted in fatalities and carries serious risk.
