ten kilometres of the Gorge, visitors can encounter a variety of cultural and natural values that, elsewhere in the region, would require considerable travel to experience; significant Indigenous cultural sites and rock art sites, narrow sandstone canyons, extensive sandstone cliff lines, basalt-capped tablelands and mountain ranges, and relict rainforest vegetation. Tracks, trails, and sites There is a ten kilometre (10 km) track leading into Carnarvon Gorge, with diversions into specific sites such as the Art Gallery, Big Bend, Wards Canyon, Cathedral Cave, the Amphitheatre and the Moss Garden. In the mouth of Carnarvon Gorge, there are another five sites to visit; Boolimba Bluff, the Nature Trail, the Rockpool, Mickey Creek Gorge and Baloon Cave (closed due to bushfire damage in December, 2018). Several remote tracks exist for experienced walkers; the Ranch, the Devil's Signpost, and Battleship Spur. Rocks and landscapes Situated within the Central Queensland Sandstone Belt, and separating the Consuelo Tableland and the Great Dividing Range, Carnarvon Gorge's landscapes have largely been shaped by water erosion. Over the last twenty seven million years Carnarvon Creek, which winds for over , has carved down through six hundred metres of stone, exposing rocks from three significant phases of Queensland's geological history including two sedimentary basins, the Bowen and the Surat, and the Buckland Volcanic Province. The youngest rocks in the area are the igneous basalt rocks of the Buckland volcanic Province which were laid down between 35-27 million years ago to depths of up to 300 metres. The basalt layer is present on top of the high country either side of the Gorge where it protects the landscape from erosion and generates significantly different soils to those derived from the lower sedimentary rocks. Boulders eroded from the basalt layer dominate the Gorge's waterways due to their ability to resist water erosion better than the sedimentary rocks they once overlaid. The most visible rocks in the Gorge belong to the Surat Basin, which holds most of Queensland's gas and oil and significant amounts of groundwater. The Surat Basin forms part of the Great Artesian Basin, and generates numerous springs within the Gorge. The oldest component in the Surat Basin is the porous Precipice Sandstone, which forms the Gorge's spectacular cliffs. The Precipice Sandstone is one of the primary intake beds for the Great Artesian Basin, giving the area where it lies exposed significance as a replenishment zone. Below the Precipice Sandstone, the
