The most spectacular of the region's caves, Jewel Cave has an impressive 5.9m straw stalactite, so far the longest seen in a tourist cave. Fossil remains of a Tasmanian tiger (thylacine), believed to be 3500 years old, were discovered here. It's near the south end of Caves Rd, 8km northwest of Augusta. Access to the cave is by guided tours that run hourly.
