Drive from the dry savannah plains to Cardwell on the coast, taking in the Wet Tropics World Heritage Area and a former logging trail, considered to be one of Queensland's great engineering feats. Start at Undara National Park to see the world's longest lava tube and travel along the Kennedy Highway, turning right into Gunnawarra Road, just four kilometres before Mount Garnet. Take Kirrama-Cashmere Road to Blencoe Falls which drop 90 metres into a pool before cascading a further 230 metres into Herbert River Gorge. From the camping area, the five kilometre Jabali walk goes to Blencoe Falls and Herbert River Gorge lookouts. Nearby is The Wet Tropics Great Walk, a multi-day hike following the Herbert River. The Kirrama Range Road in Girringun National Park has a long Indigenous and pioneering history, and features bridged creek crossings, a roadside waterfall and wide elevated views of the valleys. At Tuckers and Murray Valley Lookouts are signs detailing the history of the road. A boardwalk at Society Flat in Kirrama National Park takes you past kauri pines and rose gums which were logged in the area, showing the difference between open woodland and dense rainforest as well as logged and unlogged areas.
