Fern Pool is just above Fortescue Falls in Dales Gorge, on the eastern side of Karijini National Park. Descend the staircase into this ancient cavernous gorge and follow the clear path for 300 metres from Fortescue Falls.
To reach this tropical oasis from Perth, you can take a two-hour flight to Paraburdoo or Newman (two to three hours drive from Karijini), or a 15-hour drive via the Great Northern Highway.
Enjoy a picnic lunch overlooking Fern Pool or Fortescue Falls, follow the four-kilometre trail to Circular Pool for a second swim, or take the Gorge Rim Walk for an eagle's eye view of Circular Pool.
