Tnorala/Gosse Bluff Conservation Reserve Tours and Tickets

In a landscape strewn with otherworldly formations, Tnorala (Gosse Bluff) Conservation Reserve stands out. An almost perfectly circular crater measuring 3 miles (5 kilometers) across and surrounded by 650-foot (200-meter) rock walls, it’s the last traces of a comet or asteroid that smashed into the ground around 140 million years ago.
