At Katherine Gorge (Nitmiluk), we take advantage of the boat cruises on offer and go for a three gorge cruise, rather than going on a walk like we've had no alternative to back in the gorges of the Kimberley. We still do one short walk, up to a lookout early in the morning, but before the day hots up (to about 36C). The second gorge is the most impressive of the three that we visit (the first, second and third gorges - all that are accessible by boat). The high cliffs tower up above us and our guide points out many interesting features, including how torrential the river gets during the wet season (the photos we later see of the gorge during the record 1998 floods are impressive). We stop for a welcome swim on the way back, in a pool between the first and second gorges, and also unexpectedly get to see some Aboriginal rock art, our first on the trip.
