Depending on the season, head out on an early morning cruise along the inky waters of Katherine Gorge, or canoe between red rock walls that are up to 70 metres high (both of these activities are optional and at your own expense). This 23 million-year-old landscape was formed by the Katherine River, which flows from Arnhem Land out to the Timor Sea. Then it's time to head into Katherine where you will have the opportunity to pick up some lunch and enjoy a quick dip in the Hot Springs before the final drive back to Darwin, where your adventure comes to an end on arrival.
