Karijini National Park in WA is one of the largest and most photogenic national parks in Australia. The park is famous for its sheer gorges, waterfalls, sparkling rock pools and cool swimming holes. Karijini is about 275km south of Port Hedland and 100km east of Tom or Paraburdoo. The park is all about exploring serpentine tunnels of marbled rock, clambering over boulders, squeezing through narrow tunnels, inching your way along ledges, paddling through subterranean waterways and descending deep into chasms which have been eroded into the landscape over two billion years.
